Do I need to configurations to protect jellyfin if I just want to run it locally?

No.  Since it isn't publicly accessible, there are no additional steps needed to secure it.

Awesome thanks that's all I really wanted to know, I don't know much about servers, ports, and what keeps the local or not so I wanted to make sure it was safe to do before going in head first not knowing what I'm doing. Appreciate the help.
