Another common theme is growth. The characters grow up in the original series, but fanfiction can show even more of their personal growth. Hermione might become an even more powerful witch, Harry could further develop his leadership skills, and Ron might overcome more of his insecurities. This exploration of their individual growth while still maintaining their group dynamic is really interesting in a lot of the fanfictions out there.
Adventure themes are quite popular. They could be on a quest to find a lost magical artifact or to solve a mystery that threatens the wizarding world. Another theme is relationship - centered.
