Ali... possible sources

under nourished machine

large sized imagery

tools that are being used

basemaps

location of data (local, network etc)

Too many reasons why things may be slower than you want.

You can rule out some of the above, by repeating the workflow altering one of the above

• repeat with a much smaller dataset
• add to that, use the smaller dataset from a local drive
• try with the small dataset on a better spec'ed machine

Details on your situation may provide some targeted suggestions

• For your first image, welcome to the club (the wait while Pro slowly crawls every folder club). https://community.esri.com/thread/224063-arcgis-pro-slow-to-load-foldersfiles might have some useful context;
• Second image, welcome to the first time you open a GP tool and wait club: not sure I'm using the right phrase here, but I think it's something to do with "Building the GP cache" that causes GP tools to "hang" when opening them. 
• Last image: add your use-case to https://community.esri.com/ideas/16481-see-fields-while-scrolling-through-attribute-table-in-arcpro and https://community.esri.com/ideas/13727-scrolling-the-attribute-table-in-arcgis-pro
