Their track record is also good I would say. Fairphone 2 started with Android 5 and it currently offered Android 10 upgrade.

Recently switched from FairphoneOS (the stripped, bloatfree, google-free Android) back to stock Android¹
Its updates are fast, steady and consistently good (and improving). The FP1 is ten years old, and still works (though android there is EOL and old, and spare parts no longer available), my FP2 and an FP3 work fine, I can still get parts and Android isn't too old. The hardware is slow, and old, though (e.g. no 5G, power hungry BT, puny camera by current standards). The FP4 is top notch. Spare parts are cheap (e.g. Replaceable battery only €29, new screen only €80), android 12 good enough. But it does have stuff like Google Meet or TV that I would like to remove but cannot.
¹I'm diabetic. Monitoring and Pump control is moving from dedicated electronics to native apps. And they often require Google Android, cannot or will not run on degoogled android. Same for banking and payment apps.
The only reason I sold my FP4 and went back to samsung and their android experience was that everybod kept complaininh about mic quality during calls and I couldn't seem to fix it. Seemed like others also had similar issues
It's based on a LineageOS, but they already have added all the apps and services to use it seamlessly.
I'm pragmatic though, I think Googles services (some, certainly not all) are just so good that I think paying with my data is OK. Like Google Maps. Even though I contribute to OSM, I think all the OSM apps range from "completely suck" to "fancy, but not on par".
I think find the camera poor though. It takes passable pictures in good conditions. Do you have a better camera app that does a better job?
I use both android stock photo app and openphoto (more to tweak).
I think the pictures are good. I'm also old-school in that I think composition, focus, cutout, subject matters far more than pixel quality.
My wife, also FP4 user, sold her canon DSLR 800 (I think?), used for product images in her webshops, because the FP4 made pictures that were just as good or better, without all the hassle.
Fairphone 3 users despite still having "support" until next year are over a year behind Qualcomm and run the end of life Linux 4.9 kernel.
