Looking for fantasy academia recs

I love the magic school/academy trope in fantasy. Harry Potter will always have a special place in my heart for introducing that to me. However, I mostly see it in YA or romantasy which can be entertaining but usually lack something in writing or substance. For example, I liked the first half of poppy war for this but ultimately didn’t connect enough with the characters and story despite its length. In the pure entertainment category, I would put fourth wing which has also has dragons, so I was more willing to overlook any deficient writing or story telling. Ideally, I would like something adult fantasy not YA. The only thing I’ve read that comes close is the name of the wind.

Are there any other adult fantasy books with academy settings? Doesn’t need any romance if the story is great like Mistborn. Other fantasy I enjoy includes the Riyria Chronicles, WoT (only on book 5 so no spoilers please!), ASOIF, His Dark Materials, Gentleman Bastards, Codex Alera, and the first law trilogy (though I would love something less depressing lol). Bonus points for dragons or other awesome mythical creatures and an interesting magic system! I love books with a deep lore and training arcs especially if the protagonist isn’t all powerful
