Advice on degoogling

I'm looking into dumping googlified android with the upcoming lockdowns.

I'm a beginner-intermediate with FOSS tech: I use Ubuntu as my main machine at home, and have Lineage on a couple of old phones that I use for things at home. I use Fdroid a lot, and have things like newpipe as well on my basic Chinese handset, along with google services.

I can't really handle bleeding edge things very well, and I'm aware that even stock android isn't perfect. Just looking for options/advice.

I understand some banking apps etc will be difficult to run outside of google, and this is something that will be tough, but I'm prepping for it.

Graphene seems to be the most popular, but at this stage my understanding is it only works on Pixel phones. I'm also aware of fairphone. I know that lineage is supported on some Oneplus phones, but I don't know how safe/secure that might be.

I know that most things aren't really 'secure' in the sense that companies all snoop, but I'm thinking about things like banking or NFC payment, which I sometimes do use.

Any advice would be helpful, even if it's just confirming that the price of escaping google might be giving up a lot of this functionality right now....

Thanks in advance!
