Graphene runs on pixel and has a step by step guide on how to install it. You can also put your banking apps in another profile with Google Play services in it or run Google Play services in a sandbox on your main profile (I believe you can set that up when setting up the phone it’s just a toggle switch).
I will say my pixel 6 runs significantly better with graphene than my 8 does with regular Android and it was easy to install to test drive. I did have an issue with Android Auto but I have to check again to see if I fixed it.
Good luck! I still have to change things more then Google keyboard but it’s definitely improved
