I'm on a pixel 8 with 256 similar to your other reply. Graphene is supporting back to early pixels and has weekly updates so I don't think phone age makes a support difference, I just went with the newest reconditioned one I could afford.
I use signal, Lemmy (Thunder), NewPipe (for YouTube), Aegis auth, banking apps (but check forums on specific banks).
Losing Google Pay made me feel like a peasant for a while, I now have a case that carries cards and feel fine.
I switched from Vanadium to Iron Fox because I like the extensions, uBlock and Consent-O-Matic.
