Depends. You def wanna get an F-Droid client. I recommend Neo Store (you can find it on GitHub) it's wayyyy better than the official F-Droid app.

Once you have it go into settings > repositories and activate the ones you like. I definitely recommend IzzyOnDroid it's way better than the official F-Droid repo.

The rest comes down to if you want a de-googled phone or not. Remember if you do install Google Play Services it's all sandboxed on GrapheneOS.

You can also install them in a second user which is totally walled off from the main one.
