One common theme is the clash of different power systems. You have the magic from Harry Potter and the superpowers from the Avengers. Another theme is teamwork. It's about how the characters from both universes learn to work together. For example, Hermione might use her intelligence to help Iron Man with some tech - magic hybrid problem.
A really cool storyline could be where Doctor Strange opens a portal to the wizarding world by accident. The Avengers then find themselves in Hogwarts. They are initially confused but soon realize they need to work together with the wizards. For example, Hulk could befriend Hagrid and help him with some of his more dangerous magical creatures. And Black Widow could train some of the Hogwarts students in combat skills, while the wizards teach the Avengers some basic defensive spells.
Iron Man's technology could be combined with the magic of the wizarding world. For example, he could use his repulsor rays along with a magic amplification spell. Harry Potter's ability to use the Patronus charm could be used in tandem with Captain America's leadership skills to inspire the combined group in a battle.

One idea could be that the Avengers are somehow transported to the wizarding world. They might be initially confused by the magic but then start to work with the Hogwarts students and teachers to fight a common enemy, like a dark wizard who has also harnessed some sort of Muggle - like technology to become even more powerful.

Character development is key too. When characters from both series interact, it should feel natural.

Stark might be impressed by Hermione's intelligence and magic, while Hermione could be intrigued by Stark's technological genius. Good crossovers also explore how the characters grow and change as a result of interacting with a completely different world and set of characters.
