connection failure with some repo unavailable and database issues in the logs

That connection error wouldn't prevent the server from starting, but the database error would. If I had to guess, Jellyfin itself is fine but the playback reporting plugin, which has its own database, is corrupt. Rename or delete the playback reporting plugin's database file.

In the directory you mounted /config, go to /config/data/ and rename or delete playback_reporting.db.

Then start the container.
