If you're seriously looking at Gitea/Forgejo, I run Fjord, dedicated managed Forgejo, so you don't have to operate it yourself. We can help with migration and runners too. We also run a free public Forgejo instance if you just want to kick the tires first.
Thank you for your work on Fjord! We're currently evaluating it vs. self-hosting, the comparison at https://fjord.sh/compare has been very useful
