Uber, Google Maps, VoLTE, VoWiFi, and eSIM work. You may need to install the sandboxed Google Play Services from the Apps app.
Android Auto is completely disabled as an opinionated security measure.
Google Pay and some banking apps (ones that require Google's Play Integrity API) will not run. GrapheneOS doesn't attempt to spoof these APIs because they are moving towards cryptographic verification [0]. Most apps don't require this check but if they do you are out of luck unless you can get the app developers to trust GrapheneOS's keys.

I don't think it's accurate that there is "no way" to "prevent your mac from using the headphone's microphone." There are several workarounds like creating an Aggregate Audio Device in Audio MIDI Setup [0] or disabling HFP [1]. I wish you success with your paid utility though.
