So as a relatively fresh Fedora user (2024) who just sold their Windows PC (2025) and is in love with the OS, where would be a good place to look for areas to contribute in? Is there a place where Fedora maintainers write down what parts of the pipeline are in need of volunteers?
There's a guide! It's here: https://docs.fedoraproject.org/en-US/project/join/ (or: https://fedoramagazine.org/how-to-contribute-to-fedora/)
Personally I feel a good way to get involved is to test updates in bodhi for those packages you care about, or to take part in the process that happens around release time where we go through several freeze cycles and have 'blocker bugs' that need their fixes to be validated: https://fedoraproject.org/wiki/QA:SOP_blocker_bug_process
I would recommend to look at Fefora's infra "backlog": https://forge.fedoraproject.org/infra/tickets/issues
