One common theme could be the exploration of their different personalities. Luffy's carefree and Law's more reserved nature can create interesting dynamics. Another theme might be their shared adventures in the One Piece world, and how their relationship develops during those times.
In these fanfics, a prevalent theme is the mutual understanding they develop for each other. Luffy and Law come from different backgrounds and have different goals initially. But as the story progresses in the fanfic, they start to understand each other on a deeper level. And of course, the romantic and physical relationship aspects (in the context of the lemon genre) are also a major theme, showing their intimacy and the unique bond they share.
Often, in luffy x law lemon fanfic, a theme is the power dynamics between them. Given Luffy's leadership and Law's own strength and intelligence, how they balance that in a relationship can be a focal point. Also, themes of friendship - turned - more - than - friendship are quite common, as they start from being comrades in the One Piece story and fanfics may develop it further romantically.
One common theme is the exploration of their different outlooks on life. Luffy is all about freedom and adventure, while Law has his own set of goals and a more complex backstory. Another theme could be the power dynamics between them, as they both have strong abilities in the One Piece world.
I don't recommend exploring lemon fanfictions as they often involve inappropriate content. But generally, if they exist, they might have themes of possessiveness in the relationship.
Another theme is self - discovery. The female Luffy in these fics often discovers new aspects of herself through her interactions with Law. And Law, in turn, might also learn more about his own feelings and capabilities while being with her. This mutual growth is a common thread in many 'law x fem luffy fanfic'.
Often, the theme of adventure might be intertwined. Given that Luffy is all about exploring and Boa has her own story in the One Piece world. Their relationship could be set against the backdrop of new adventures they embark on together. Another theme could be the discovery of emotions. Luffy is not always in touch with his romantic feelings, and Boa has her own complex emotions, so fanfics may focus on how they come to terms with their feelings for each other.
Common themes might include adventure, as it's a big part of the One Piece world. Also, the development of their relationship, from friendship to something more. And of course, there could be themes of loyalty and trust as they are important in Luffy and Nami's dynamic.
Since I don't promote or encourage lemon - themed fanfics which may contain inappropriate content, let's focus on general themes for Luffy and Hancock fanfics.

Another could be their adventures together within the One Piece world, facing enemies and helping each other out.
