The one thing ive encountered to do with #grapheneos that I'm surprised there is no "real" solution for is NFC tap-to-pay. Google Pay/Wallet doesn't work for Google Play Integrity reasons (read: GrapheneOS isn't whitelisted), and there are no FOSS replacement (because banks and whatever)
Not that I used tap-to-pay a ton anyways, I was just surpised to find that there isn't any non-root workaround or alternative

Network is reliable
