How to snip off a portion of layer like ZIP or Census Blocks?

Question

It has been established that AGOL has access to some good boundary layers on the Living Atlas and other places.

How do I "snip a portion off" of these system layers?

Let's say I put on the ZIP layer, and I want to snip off just the ZIPs that are within some boundary...like the city of Phoenix or the CBSA.

What is the workflow?  Every time I try to use an operation like "intersects" it doesn't do it?  I need to end up with a separate layer with just the stuff I want in it.  I want to display and enrich just the resultant features, not the whole thing.

Bonus question:  why does BAO have an ESRI 2020 pop layer, but AGOL only has ESRI 2020 pop density layer?

Thank You.

Actually, I figured this out.  Using the "intersection" operator on the ZIPs with my other polygon works fine.   The result layer sadly does tack on the thing on the outside that share a line segment with my polygon. I didn't realize the reason I could edit this resultant polygon is that it was locked by default.  Unlock it, and snip away the odd ZIP that I don't need.  Very weird how intersection and "within" operators seem to be equivalent for polygon vs polygon operations.

What I was after was a good "clip to path" type operator. AGOL just doesn't have the full suite from Pro.
