I have an android phone with a custom UBPorts build maintained by an XDA forums member. It runs many android apps very well within anbox. I have tested many apps from F-Droid with success. Even the android buttons (recents, go back) work which is very convenient in android apps.

Right now the performance is better than on my pinephone but there are also some issues, like Libertine not working correctly.

The main issue with anbox right now is that video/audio playback does not work. Apps like NewPipe and AntennaPod run fine except that no playback is possible (results in blackscreen).

Dual booting a linux distribution with something like glodroid seems like a promising solution!
