I would love to go no Google Play services but I can't go without some apps such as "Mobile Pay" (money transfer to people or stores), "PostNord" (open unmanned package delivery box), and "EasyPark" (registration and payment for parking car).
Here is a list of my currently installed apps through F-droid:
Acode (using it as a simple text-editor)
AndrOBD
DAVx5
Etar
FlorisBoard
K-9 Mail
Mull
NewPipe
Open Camera
Organic Maps
PCAPdroid
QKSMS
Session (Sessions own F-droid repo)
Simple Notes Pro
Simple Voice Recorder
Syncthing
When I switched to GrapheneOS I was surprised how many FOSS apps could replace apps from Google Play Store and how some apps are totally replaced with just my browser (e.g. listening to radio)
