For pleasantness and YA high fantasy vibe Le Guin's Earthsea Cycle is great.
For wizard school with a much more mature tone R.F. Kuang's Babel is a great read. Warning though it is much darker and heavier, so prepare yourself emotionally haha.
EDIT: was recommended that I give a heavier content warning to Babel which is fair. While it is thrown around as an HP alternative it is emotionally harrowing, has some extremely violent and disturbing sections, and is generally focused on depicting the horrors of colonialism. A good read, but prepare yourself going in and don’t expect it to be quaint or pleasant.
