I also have a PS5 controller, as far as I understand, haptic feedback is not humble, it is a resistance in the triggers (L2 and R2) só a game can make pull the trigger be harder of softer depending on the situation.
I don’t know how many or which games uses it seem how many games still does not correctly display PS controller icons and etc and fallback to the MS iconography.
As far as I know haptic and maybe the mic/phone are the only things that does not work over BT. But I also think I read that some things that does work with BT does not work over USB
