Unfortunately, remote attestation in the form of SafetyNet (and friends), killed the custom ROM scene for many.

Aren't there ways of getting attestation working even with custom ROMs? (never tried, but I think I've read something about it in the past)

There are hacks, but they're not reliable and break with every major Android version.

I feel like there hasn't been so many viable custom ROMs ever: GrapheneOS, CalyxOS, LineageOS, /e/ OS, DivestOS, ...

I use one of them, my phone came with it, and I never had to do anything special with it. It just works. In my case it's de-Googled so I just have to use alternatives apps for e.g. Google Maps and the likes.
