Ah, ok, you're talking the difference between a rule-lite approach, ala 13a and Shadows of the Demon Lord (naming two of my favorite rules-medium/lite games), which is what 5e embraced, for the most part, and rules-heavy approach, which has been Pathfinder's wheelhouse.
I definitely don't mind rules-lite games. In fact, I prefer them, especially when they have include substantial character customization options. 5e, which I think is my favorite version of D&D, doesn't fall in that category. Sure, there are dials you can crank to change effectiveness, but those dials are few in number, and the effect is too radical for my taste- it makes certain builds the "right" build and the whole host of others the "wrong" build.
You are absolutely correct in criticizing PF2 from a rules-lite perspective- it isn't rules-lite. But it wasn't ever intended to be, so there really isn't much point in continuing this part of the discussion- you're right, it's not rules-lite, which is as intended- a good chunk of people like to have definitive rules on crawling, which opens up space for feats that modify it.
