I just switched to a Fairphone 5 with e/OS, which is a de-googled Android (it uses microG), and am pleasantly surprised how well everything works. My banking apps work, contacts and calendar lived on nextcloud already, the learning apps I use work.
The two things I have to get used to is not having google maps, but the map app on there has also worked fine for me so far. And casting to a Chromecast doesn't really work for me, but I can live without that.
