I think the story of Cinderella can actually be a very good choice, it can be seen as a story of abuse.
So, Cinderella could actually be a high ranked, talented, smart and kind noble kid that has potential of be great, perfect even in her studies but her stepmother and daughters can't compare to her talent, so they pretend she died with her father, lock her up in the house and have her clean and work like the house attendants. The fairy godmother could be an aunt that discovers that she is alive and tries to help her get out discreetly by helping her go to the ball of another high ranked young noble that's looking for a wife.
Ok, here ends my rant, thanks for reading ig.
