Well, perhaps the main character is a solo player who is really good at combat but is now stuck as a girl. This change could make him/her re - evaluate their combat strategies as different genders might be expected to fight in different ways in the SAO world. Or it could be a group - oriented player who now has to deal with how their new gender affects their relationships within the group. There could also be non - player characters who play important roles in helping or hindering the main character's journey while they are stuck as a girl in SAO.
In a 'stuck as a girl in sao fanfic', the plot might revolve around the protagonist's struggle to adapt. They might initially be shocked and confused about their new form.

Sakura could be one. She's a skilled ninja and also Naruto's friend.
