And to your original question, yes, the stucco should be directly over the concrete, very similar to our concrete/block home. I would go with longer plastic inserts, so you have some grip in the concrete and not just the stucco.

A 1/4” impact drill works much better than trying to drill in concrete with a regular drill (which doesn’t really work). However, I also have a DeWalt 1/2” hammer drill, 20v, and with the right bit, that zips through concrete block and is pretty fast on solid concrete. There was a time, though, when I needed to pass a garden hose through a solid 8” concrete wall. I think I used. 3/4” hammer drill, and I was through in about three minutes. These tools can be rented. You don’t use them very often.
