You can use the GP tool Delete Rows to delete the selected (or all) rows of a feature class like the Facilities or Incidents.
If you have the feature attribute table open, you can select rows and right-click and choose Delete Row.
Also, if you are re-using a CF layer to load another set of facilities or incidents, you can on the Add Locations tool turn off Append To Existing Locations and that will delete the previously loaded data and add new locations.

You should use Maximize Capacitated Coverage. This will look at the capacity. The option you used to Maximize Coverage and Minimize Facilities is about maximizing how much demand it can cover in the cutoff distance. It does not look at the capacity settings.

Do you have your own local copy of the Streetmap Premium that you are using? Not AGOL. I tried using AGOL with your data and scenario and the route worked fine. Gave me a route with 475.5 Km.
It could be an issue with the version of SMP data you have and the hierarchy settings. So, try turning off hierarchy and then resolve. The hierarchy setting is on the same area when you are changing restrictions, expand the advanced section and turn hierarchy off.

One possibility is to translate the dump cost dollars into travel miles. So, if you assume that a dump truck travel cost is $5 per mile then the dump site with cost of $75 should be delayed 15 miles and a facility with $200 cost would be delayed by 40 miles, assuming you use a driving distance cost attribute (not travel time) to solve the service areas.
Other possibilities that do not involve service area is to use the OD Cost Matrix solver to generate distances/travel times between the facility locations and your start locations and then do some post process to answer which location goes to which facility.

In service area, the facilities can be loaded with a "delay" in terms of the cost attribute being used to solve the service area. For example, if you want to do a 4 minute service area and a facility was set to have a 1 minute delay then it will only create a 3 minute service area. The "delay" is per facility. Here is a screen shot of three facilities with delay set to 0, 1 and 2 and the subsequent 4 minute service areas.
You need to set up a network dataset with a cost attribute set up in terms of $ per mile then you can use the delay concept to load the facilities with the trash fee at that facility and generate your polygons.
However, if you are planning to use the online service, it does not have a cost per mile attribute.

It is not clear what you are trying to achieve. You have locations of dump sites and prices in the first picture. In the second picture you have two start locations and two dump sites. The price of $25 per mile adds another variable. If a consumer is trying to make a decision than they would simply go to the "nearest" dump site minus the price they pay. So Point B can go to the $75 dump as long as the distance to that dump is less than 5 miles after which the dump with $200 price is cheaper. What kind of polygons are you trying to produce? What defines a "polygon"?

Generally speaking, there is no setting on Location-Allocation to set a minimum threshold on a facility. However, you could screen sites that are not feasible. For example, you must have some sort of distance or travel time constraint for reaching the 1000 people, eliminate the candidates that do not have a 1000 people within your cutoff. Not saying that this will give you the desired results, just improves the chances. You can also do an iterative approach. Solve for X sites, remove ones that do not meet the minimum criteria and solve again. Regards, Jay Sandhu

The wait at a traffic signal depends on when the car arrives there and also which direction it will go, i.e., straight, left, right or U-turn. So how are you modeling the delay? One way is to simply delay the overall speed/travel time on all the edges or add a user junction at the traffic signal junction and add a junction delay in the network dataset. Or use the turn category evaluator in the network dataset to set up the delays. More info here: Turn category evaluator—ArcGIS Pro | Documentation Jay Sandhu

If your goal is to delay a path, and you have that path as some line feature, then you can load it into a route analysis layer as a Line Barrier with scaled cost. Set the cost with the amount of delay. See more here: Barriers—ArcGIS Pro | Documentation Jay Sandhu

It is hard to say what could be going on. Are you using the online logistics service or local street data network? Perhaps the street data has an invalid spatial index causing the search to be slow or access to the data is slow if it is on an external/cloud drive. You can try creating a fresh project and recreating the layer and see if that fixes the issue. Beyond that you will need to share the VRP layer/data with tech support so they can help diagnose what could be going on. Jay Sandhu

Are you solving a Location-Allocation problem or Vehicle Routing Problem? How many inputs are being added? i.e. the size maybe large and it might be computing a large cost matrix to start the analysis. Jay Sandhu

Generally you can use the Location-Allocation solver for warehouse locations. It will minimize distance to the places you want to deliver to. The inputs are the location of your demand points (places to deliver to) and the candidate facilities from which you can pick your warehouses. You need to use your consumer characteristics and anything else that is important to find a list of suitable candidates that you can input to the location-allocation solver and then solve for the optimal number based on how far you want to deliver to (cutoff).

The features that make up a network dataset can be true three D. That is polyline with Z. However how you take the 3D and turn into useful network costs is up to you. For example, you can compute slopes for each line and use it come up with your travel cost based on vehicle type. Do note that DEM's do not have built features, so you will not be able to figure out bridge heights or tunnels on a road based on a DEM. So, yes, you can add terrain attributes to a network dataset like any other cost, restriction or descriptors and use them in routing. Jay Sandhu

Glad you found a way to solve your problem. There are a couple of tools that can help create points inside polygons. First, you can use the Polygon to Raster with an appropriate cell size to create an output grid/raster. Then you can use the Raster To Point to convert these into points. These will be spread evenly within your polygon area. You can also choose to use the Create Random Points to sub select a random set from your raster points. Also, the Feature To Point tool can be used to place points on the mid points of selected roads. Hope all these tools will be useful in simplifying point creation! Jay Sandhu
