Can anyone comment on the T&C on ownership of repo content on these Git hosts? I could not locate specific mention of that on Gitlab.

Gitlab's terms and conditions for their hosted service are here; they don't really address ownership: https://about.gitlab.com/terms/

Gogs isn't a hosted service; you're installing it on servers you control, so you retain ownership of your content. (I suppose there would be questions about ownership if you uploaded content to their demo instance at try.gogs.io, but you probably shouldn't upload things you care about to a demo server like that.)
