Nothing beats Google Photos for me, personally.
So I bought a used Google Pixel 1 (first gen) and use Syncthing to sync my camera roll from my phone to the Pixel 1.
Google originally advertised the Pixel 1 as having unlimited cloud storage for life, so they have to stick to it. I don’t pay for Google storage but I’ve got at least 500gb stored in Google Photos (including all my RAW photos and my digitised VHS tapes).
I’ll abuse this system until the Pixel 1 dies and I can’t get another one, then I’ll cry.
