For what its worth, my banking app has worked without a problem on GrapheneOS with the sandboxed play store. Truly loving it. (I also went in with a backup and would suggest it just in case).

My two banking apps have run fine on LineageOS with microG. There are plenty of other things that don't work, but the banking apps are fine.

Maybe give GrapheneOS a shot then. In my experience, pretty much everything works out of the box.
