One common theme is the resolution of their differences. Since they had major conflicts in the movies, fanfic might use a kiss as a way to show them making up.

A third common theme is sacrifice. Fanfictions may depict situations where either Captain America or Iron Man has to sacrifice something for the greater good or for the sake of their relationship.

Another theme is the sister's own journey of self - discovery. Since she's related to a famous hero, she has to find her own place in the world. This could involve her developing her own powers or skills, like learning martial arts to be able to protect herself and help her brother. It's about her growing as a person while being part of Captain America's story.
