One common theme is protection. Luffy is always ready to protect Nami and in a family - fanfic context, this extends to protecting their 'family' within the crew. Another theme is growth. As they form a family - like bond, they both grow as individuals. Nami becomes more confident in her decisions and Luffy learns more about the importance of relationships other than just being comrades.
One interesting theme could be the exploration of loyalty in a different context. In the original story, Luffy and Nami have a strong bond of loyalty as crewmates. But in a fanfic, this loyalty could transform into a more romantic and exclusive loyalty towards each other. Another theme might be the discovery of self - through their relationship. Nami could learn to trust more deeply, and Luffy could become more aware of his own emotions.
Adventure is also a big theme. Since they are pirates, many fanfics will take them on new and exciting adventures that might not be in the original story.

The stories might show how Nami's navigation skills and Luffy's fearless leadership combine to get them through these adventures.
One common theme is friendship. Their strong bond as nakama is often explored. For example, how they support each other in battles or tough decisions.
