A prevalent theme is the exploration of identity. Peter has to balance his identity as Peter Parker and Spiderman, and in fanfiction, this can be further explored especially in relation to MJ. Also, the theme of friendship is common. How Peter and MJ's friendship with other characters, like Spiderwoman if she's included, is often a part of these stories. For example, they might team up with Spiderwoman to save the city.
One common theme is the struggle between Peter's superhero life and his relationship with MJ.

One common theme is the exploration of an unlikely relationship. Given the different natures of the two characters, seeing how they come together can be fascinating.

Love and support is a very common theme. MJ is often shown as a pillar of strength for Peter, and he in turn gives her a sense of adventure.

A common theme is the battle between good and evil. Spiderman represents good and Carnage represents pure evil. Another theme is the struggle for power.

One common theme is alternate universes. Writers like to explore what would happen if Spiderman had different powers or if the events in his life took a different turn.
Good character development. If the fanfic allows MJ to grow as a character, perhaps she starts to learn self - defense to be able to help Spiderman better in dangerous situations. It also applies to Peter's growth in his relationship with MJ, like learning to be more open about his feelings.
There is also 'Love in the Shadows' where the fanfic delves into the more private moments between Spiderman and MJ. It explores how they keep their relationship a secret from the outside world, adding an element of mystery and tension to the story.
Well, there are various storylines. Sometimes they face villains together, and at other times, Spiderman tries to balance his love for MJ with his superhero duties. There are also moments of doubt and challenges in their relationship.
