For banking, I use the website instead of the application. I have very few non-open-source applications left on my phone.

If you still use your Google account to synchronize your contacts and calendar, you can move them to Nextcloud too.

I don't know if there exists such a thing as GrapheneOS account, but it is not required. You can add Google, Facebook or other accounts like with regular Android. I use a self hosted Nextcloud instance to synchronize contacts and calendar with DavX5 app. GrapheneOS has built-in apps. I use most of them. For the app stores I mostly use Fdroid and Aurora store for non open source software. I don't use Google play store even sandboxed because I don't accept the terms of use, mostly because they have the right to uninstall apps from your phone without consent or notice.
