Fairphone

I am looking at getting a fp4. (Pretty seriously, I am typing this on an older phone because I listed my newer phone on eBay to switch) I want a good, privacy focused operating system to run on it and was wondering what you all run and what your experiences have been. My main concerns are:

1. Support - I don’t want my operating system maintained by just 1 or 2 random people on github.

2. Features - I want the basic stuff to work but am concerned about the fingerprint sensor and cameras.

3. Privacy - I want something ideally completely degoogled.

4. Stability - I don’t know much about android but I use Debian lts if that tells you anything about the kind of update schedule I want.

I know this is a lot to ask of an os but do you have any recommendations?
