The deviation from the original story makes it interesting. In the original Hunger Games, Clove doesn't win. So when she does in fanfiction, it's a whole new take on the story. It allows for exploring different aspects of her character.
She might have to deal with a lot of trauma. At 12, she's still a child. Maybe she'd struggle to adapt back to normal life in District 12. The Capitol would surely keep a close eye on her as such a young winner, which could lead to more problems for her and her family.
One possible plot could be that Prim uses her knowledge of herbs and medicine to create traps that either incapacitate or mislead other tributes. She could also form alliances based on healing others in return for protection. Another plot might be that she finds a hidden area in the arena that has abundant food and water sources, and she manages to defend it against other tributes.
One common theme is redemption. Since Cato is often portrayed as a brutal fighter in the original story, in fanfiction where he wins, he may seek redemption for his actions during the Games.
There are several fanfiction pieces out there. Some might focus on Clove forming unexpected alliances that help her win the Hunger Games. For example, she could team up with tributes from different districts who share a common goal against the Capitol. By using her wits and her proficiency with knives, she could outsmart the other tributes in these stories.
