I'm literally posting this from a grapheneOS pixel on the ruqqus app. Install fdroid and Aurora droid for Foss apps install aurora store for a googless appstore. Also a lot of apps say they need google services to run. They dont. Discord and ONX hunt are the only apps that are broken for me. My banking app, fitness apps, finance apps from the aurora store all work just as they did on googles OS. I don't even use microg as there are security concerns with it and google services in general

Also, use a unique meaningless password with a manager like bitwarden so if one site gets compromised it means jack shit for any other account
