You can enable Play Services and install them and use them, but why bother using a DeGoogled phone at that point?
I use the OsmAnd~ (OpenStreetMap Android) navigation app, which navigates great, but ...
Sandboxed Google Play is confusing because like you asked, why bother using a de-googled phone? Well, it's still degoogled when using sandboxed mode:
Built into GrapheneOS, Sandboxed Google Play lets you run Google apps (like banking apps or Google Maps) while keeping your phone’s strong privacy protections. Instead of giving Google Play Services full access to your phone, GrapheneOS runs it inside a regular app just like any other app, but it's sandboxing means it's in a separate profile with no permissions and no other apps, AND you don't have to be logged into Google AT ALL. In fact, it's an anon sign-in that's automatic. It never even asks you.
Google Play Services only gets minimal system access it needs (like checking device integrity for banks). It's a walled-in scope this way, so it cannot see what other apps are doing, or see any of your personal data.
