Well, it could be that Doctor Strange trains Harry Potter in the use of magical artifacts. Harry has experience with powerful objects like the Elder Wand, but Doctor Strange could introduce him to artifacts from different magical realms. He might teach Harry how to harness the power of an artifact without being corrupted by it. This new knowledge could help Harry in his quest to defeat Voldemort by providing him with additional sources of power and knowledge that Voldemort may not be aware of.
One possible plot could be that Doctor Strange uses his magic knowledge to train Harry in more advanced and esoteric forms of magic. Harry might learn to manipulate time and space in ways that are different from the normal Hogwarts curriculum. For example, he could learn to create stable time loops to study spells without the risk of negative consequences. This would give him an edge in his fight against Voldemort as he could plan better strategies and anticipate his enemy's moves.
Well, it could be that Dr Strange uses his magic knowledge to train Harry Potter in different ways of spellcasting. Maybe he shows Harry how to manipulate time and space while casting spells, which could give Harry an edge in fighting Voldemort. He might also teach Harry about different magical dimensions and how to draw power from them.
Harry Potter's character would develop a sense of mystery. Doctor Strange's magic is often associated with the unknown and the arcane. After being trained by him, Harry might start to act more mysteriously, keeping his new skills and knowledge under wraps until the right moment. This new air of mystery would not only add to his allure but also make him a more unpredictable opponent for Voldemort. His relationships with his friends might also change. They might see him as someone who has moved to a different level of magic, and there could be some initial distance or envy, but Harry would also be able to use his new skills to protect them better in the long run.
Well, perhaps the plot could involve Stephen Strange using his magic knowledge to train Harry in different forms of magic that are more advanced than what he learned at Hogwarts.

A possible plot could involve a new, powerful dark sorcerer who has found a way to combine magic from both universes to become invincible. Doctor Strange tries to stop him but is quickly overpowered. Meanwhile, Harry Potter senses the danger through his connection to magic. He travels to Doctor Strange's side. Harry uses his knowledge of magical creatures from the Forbidden Forest. He summons a group of Centaurs who help him in the battle. With their combined strength and Harry's strategic use of spells like the Stunning Spell, they are able to defeat the dark sorcerer and save Doctor Strange.
The magic could blend in interesting ways. Harry's wand - based magic might be enhanced by Dr Strange's more esoteric and hand - gesture - based magic. For example, Harry could use his wand to direct the energy patterns he learns from Dr Strange.
One idea could be a crossover where Doctor Strange uses his magic to visit the wizarding world of Harry Potter. He could meet Harry and help him with some of his more difficult magical problems, like dealing with a particularly powerful dark magic spell that the Hogwarts professors are stumped by.
Maybe Harry discovers some long - lost magic techniques taught by Godric. He could become super powerful and use ancient spells to fight Voldemort.

Well, perhaps in this fanfiction, Grindelwald trains Harry to be a sort of double agent. Harry would learn Grindelwald's ways so that he can infiltrate the dark wizard's followers. Grindelwald thinks he can control Harry, but Harry is secretly using the knowledge to gather information for Dumbledore. Along the way, Harry would face a moral dilemma as he has to pretend to embrace the dark arts while still holding onto his own values.
