The company that imports Fairphone 4 to the US (Murena) runs e/OS which is OK. There's a bit of FUD that pops up on HN about e/OS from time to time, but the reality is that it's a mostly de-Google'd but still usable LineageOS clone. Their emphasis is on de-Googling, and usability, not security. It's probably worth a look. I'd say that their privacy/de-Googling is the best of all the LineageOS flavors. You can see comparisons between all the flavors here:
That said, you can flash any Android Os that supports Fairphone, or PostmarketOS to it.
The phone itself is responsive/quite good despite being a bit old at this point. I can do all normal phone tasks (email, web, music, navigation, etc) with no lag or any issues. I have not attempted to game on it. The Fairphone 4 is modular, parts are available for repairs, and it works great in the US with T-Mobile or T-Mobile MVNOs.
