You do not need to setup a cleanup cron anymore as there is now an automatic cleaning process in Invidious. Since this pull request: https://github.com/iv-org/invidious/pull/3294. But this page is left in case you need to manually cleanup the database.

annotationsCaches annotation data if
cache_annotationsis enabled in
channel_videosStores truncated video info, used to create user feeds
channelsStores UCID and author name
noncesKeeps track of tokens issued to prevent CSRF
usersStores user info, such as preferences, username, subscriptions
session_idsKeeps track of user sessions
videosStores video cache, used to create "top" page

For regular maintenance you should add a cronjob for these commands
