Yes, the GrapheneOS team put a lot of time and effort into creating Sandboxed Google Play services. It allows you to use Google services which are required for many apps without giving up your privacy. You get to choose which permissions you grant to Google Play services, just like with any other app. Basically any app that works on Android also works on GrapheneOS, except for a few things like Google Pay or Android Auto, because Google actually prevents them from working on Graphene.
