I really like the fanfic 'Izuku's Hidden Power'. Here, Fem Izuku has a quirk that is initially hidden but turns out to be extremely powerful. It's a slow - burn story that gradually reveals the extent of her power and how she copes with it. It also delves into her character development, showing her as a strong - willed and determined girl. There's also 'The Empowered Fem Izuku' where her quirk is related to telekinesis and mind - reading, which creates some really interesting scenarios in the story.
One popular 'Fem Izuku has a powerful quirk' fanfiction is 'A New Path for Izuku'. In this story, Izuku's quirk is an elemental one that allows her to control multiple elements. The author does a great job of exploring how this changes her relationships with her classmates, especially Bakugo. Another good one is 'Powerful Izuku: Rising Star' where her quirk gives her super strength and flight abilities. It has an interesting plotline that focuses on Izuku breaking gender stereotypes in the hero world.
A great fanfiction in this category is 'Fem Izuku: The Quirk Prodigy'. In this, her quirk is a combination of speed and healing. It starts with Izuku being underestimated because she's a girl, but as her quirk unfolds, she becomes one of the most powerful students at UA. The story also has some great moments of friendship and rivalry, like when she competes with Todoroki in a training exercise and manages to surprise everyone with her newfound powers.
