There is also framagit: https://framagit.org/public/projects which is a Gitlab instance run by a French non-profit, Framasoft: https://framasoft.org/en/
I host my project there, no issues.
I think Codeberg's co-op style governance/funding makes a lot of sense w.r.t sustainability.
A reminder that Framasoft's a worthy cause to donate to if you are looking for causes to support!
