Sirius Black could also be an important character in relation to a female Harry. He could be like a protective older figure, but also help her understand the more complex aspects of her new identity. Maybe he has stories about her mother that are relevant to her new situation as a girl in the wizarding world.
As I mentioned before, Draco. The whole idea of a female Harry and Draco having some sort of relationship, whether it's a begrudging friendship or a full - blown romance, adds an interesting twist to the original story. Their family rivalries and different personalities create a lot of potential for interesting interactions.
Hermione is often still a very important character paired with female Harry. Their friendship could be even more complex and deep, as they support each other through the challenges at Hogwarts. Ron is also a common character paired with her. Their relationship might develop in a different way, perhaps with a bit more of a romantic undertone compared to the original. Draco Malfoy is another popular one. There could be a more interesting dynamic between them, with Draco being both attracted and antagonistic towards her at the same time.

In many fanfictions, Neville Longbottom's son or daughter is paired with Harry's daughter. Given Neville's importance in the wizarding world, their children's relationship can be really engaging. They could be partners in a herbology project, and through that, develop a deeper connection. Also, the children of Luna Lovegood are sometimes paired with Harry's daughter. They might share an interest in the more esoteric aspects of magic and go on adventures to discover new magical creatures or phenomena together.
Ginny is also frequently paired with Harry in such fan fictions. Given their relationship in the original books, it's a natural extension for fan fiction writers. When Harry finds out Ginny is his mate, it often leads to a more intense and magical exploration of their relationship, with added elements of destiny and true love.

Some fanfictions add an older wizard as a mentor figure. This wizard could have a different view on magic compared to Dumbledore and might teach Harry some more unorthodox magic. This adds a new dimension to Harry's learning about the wizarding world.

Hunk's kindness and Pidge's strong - willed nature as a girl can lead to some really heartwarming and adventurous stories.

He could be a mentor figure, but also there could be some underlying feelings as Naruto, now a girl, grows up under his guidance. And Shikamaru is also a character that is sometimes paired with 'Naruto reborn as a girl' because of their friendship and how Shikamaru might see her in a new way and develop feelings for her over time.
