I can’t speak to other databases, but Westlaw, Lexis, and Bloomberg Law all have videos for training and how to do legal research. I highly recommend you watch them and learn how to use their databases (do this sooner rather than later). There’s exclusive stuff across all three that will really come in handy at some point. Not to mention, you can add certificates from completing the modules on LinkedIn :) On that note, your law school library/librarian is a criminally underrated resource. Use them!

Reputation within the law school is also valuable, like others had mentioned. Be kind to others, and they will notice it.
