Nokia before: check out this indestructible phone
nokia now: you can now rent our climate change friendly WEF phone with below avg specs
I dont think modern nokia phones r custom rom friendly, they might've locked bootloader just like most other mainstream manufacturers, though you might wanna double check that. Even if these phones were bootloader unlockable i don't think they r gonna get any stable custom roms, niche brand which is pretty much dead now. Even more mainstream phones dont get custom rom support these days.
There aren't many good phones made in the current day. The ones that are made don't have any rom support.
