> if shit hit the fan and corrupted my Git files or stopped being maintained I'd be a duck out of water

You should have the same concern with anything you're hosting yourself, and you should have 3-2-1 backups to mitigate that concern. Gitea just uses regular Git repositories under the hood last i checked, and Git is an extremely mature system; I'd expect 20+ year old repositories to work fine as long as the data are kept physically intact.
