🧙The Books of Magic (the original run if you can get it.)
🧙‍♀️Maho Tsuki Tai (Magic User's Club, a good classic Anime.)
🧙Ikenfell (a video game actually with a lot of LGBTQA+ rep.)
🧙‍♀️Any of the Discworld books with Rincewind as the protagonist
🧙The Abhorsen Books by Garth Nix (just a fave)

There's also the So You Want To Be A Wizard series by @diane.dianeduane.com if you don't need the school part but still want young wizards.
