Forgejo is fairly simple to run – way lighter and simpler than GitLab even. (GitLab is quite okay, too!)
If you want a hosted service, go for Codeberg. It’s run by a German non-profit (so it’ll be hard to bite and switch OpenAI-style). Only free/open source projects are accepted, though.
How is Codeberg connectivity from outside Europe, nowadays?
From my experience, things are looking great from East and Southeast Asia. Why?
