A programmer in search of a repository

So far in my open source career, my biggest contribution has been helping others in the Django Discord and then becoming a moderator. I would like to broadern my involvment in open source, I have ideas around teaching others (these posts are a starting point for that).

I think I would like to help maintain a package, but I am unsure of the initial steps to get started or even which package to even pick. From what I have read and listened to, a package I know and use regularly would be likely most suitable to me. But that's where I get a bit lost, although in just writing this out I realise I would need to set aside some regular time in a week to work on a project, be in mine or another.

Any suggestions for which packages need some help?
