I've looked at several sites on the Internet, and pretty much all of them have you choose the lowest power that allows you to read a given text.

OK, but why. If +1.00 is good, why wouldn't +1.50 be better?

Is the theory that the glasses are a crutch and using the crutch allows your eyes to get lazy and therefore worse, needing stronger and stronger glasses sooner?

Or is there some other reason?

Yeah, I think I'm finally to that point.
