I am somewhat weird among my peers in this respect: I invert Y on joystick controls only (and leave it as default for mouse controls). Probably there are other people who do this - it certainly makes sense to me - but almost everyone else (invert-Y or not) seems to find this odd when I actually discuss it.

It didn't super matter until I started using a steam deck, which has both joysticks and touchpads. I usually need to reverse one or the other in the steam controller mapping, since few games let you configure invert-Y separately for different input devices.
