A common theme is friendship. They've been through a lot in the Marvel universe, and fanfictions often explore how they become true friends. For example, stories might show Bucky opening up to Sam about his past as the Winter Soldier, and Sam being there for him.
Another theme is their teamwork. They work together as superheroes, and in fanfiction, this can be emphasized. They might face a new villain or a difficult situation that only they can solve together because of their different skills. Like Sam's ability to fly and Bucky's combat skills combining to defeat an enemy.
The theme of mutual respect also pops up a lot. Given their different backgrounds and experiences, fanfictions often show how they learn to respect each other. Sam respects Bucky's past and his journey to redemption, while Bucky respects Sam for taking on the mantle of Captain America and his values. This mutual respect is a key part of their relationship in many fanfictions.
