I run a litany of Google (and other corporate/business apps) apps in Private Space under the owner's profile, which is only unlocked when I need it for something. That space's connection can go out over a WireGuard tunnel if I need those apps to be on any specific networks, while the rest of the phone's traffic is unaffected. The file systems stay functionally separate (although that's not a major concern given how file encryption is handled, plus the dream that is Storage Scopes), and that space has its own camera app and such.

The Owner profile itself doesn't run Google Play Services, so when that Private Space is locked and dormant it's effectively a degoogled stack.

Some will invariably argue that an old pocket-sized Linux PC with a cellular modem is a superior experience, and for some specific things it may well be, but GrapheneOS is the only viable option for someone looking for a user-respecting modern phone with very few limitations.
