I think best approach if you need to use privacy invasive apps like uber and so on is to have a degoogled personal phone, and second stock phone whether it is android or apple for all those other apps that don’t play well on custom roms.

Compartmentalizing is best that can be done if there isn’t much choice in not using certain apps, and cuts down on headaches of trying to get them working on custom roms. And that stock phone can just be a cheap crappy budget phone, since its main use will be to just launch those junk apps when needed.
