The allure often lies in the novelty. It's exciting to see how the story changes when Harry is female. For instance, the way she interacts with Tom Riddle can be completely different. She might be more empathetic towards him in some fictions, which could potentially change the course of his dark journey.
One plot idea could be Fem Harry growing up in the wizarding world with the secret of her parentage. She might start to notice strange similarities between herself and Tom Riddle's dark magic tendencies, but struggle against them. Another could be her discovery of her heritage leading to a conflict within the wizarding community, as some fear she will follow in her father's dark footsteps, while others believe she can break free from that legacy.
Family and heritage play a big role. She has to deal with the fact that her father is one of the most feared wizards in history. There's often a theme of secrecy as well. She might have to keep her true identity a secret from her friends. Also, power is a theme. As Tom Riddle was powerful, she may inherit some of that power and has to decide how to use it, for good or evil.
Well, in many fanfictions, fem Harry brings a new perspective to the story with Tom Riddle. Since she is female, the power dynamics and the nature of their relationship can change. Maybe she can use her femininity in some ways to outwit Tom Riddle. For instance, she might play on the prejudices that exist in the wizarding world towards women to her advantage when dealing with him. It also adds an interesting layer to the whole 'good vs. evil' concept as it's no longer just a male - male power struggle.
