I use graphene on a pixel 6a and used it on a pixel 4 and my nfc tags work fine, there are just some sacrifices on nfc payments (no google pay), but even these seem to work with other apps (i heard huawei pay app should work)

Never heard of this before. GrapheneOS has been around for a while and known well throughout the Android ROM community.

what services do you use to loop out?

Good morning nostr

Damus has had it's first rejection from Apple's App Store, but honestly this is a right of passage. I've seen this happen to many applications over the years. This is just Apple being Apple and most if not all of these recommendations can be remediated quite easily. We will win.
