Gotta step in as a GrapheneOS User. You have multiple options.
The easiest and most approachable one is: install Aurora Store from F-Droid. It gives you access to Google Play + App Updates without logging you into Google. This almost feels identical to Google Play itself.
Next: think about install the Experimental GMS Support that GrapheneOS offers. If you e.g. absolutely need an App that has troubles working without Google SDKs embedded, this might be an option. This is documented in the Usage Guide of the Website.

However, just dont forget that you wanted a Google-FREE Phone. So dont overdo installing proprietär stuff.
Oh and stay as far away from MicroG as possible, it seriouly cripples the security of GrapheneOS by a lot.
