Love could also be a theme, although it might be a bit more complex given the different natures of their respective stories. Maybe it's not a romantic love at first, but a love for each other's strength and the way they face challenges. The fanfic could explore how they come to respect and care for each other in a way that goes beyond just a simple acquaintance, and perhaps over time, that could develop into a deeper form of love that is unique to their combined story.
The theme of redemption is also seen often. Leah has made some mistakes in the Twilight story, and fanfics might show her trying to make up for those mistakes and become a better person. There's also the theme of family. Some fanfics explore Leah's relationship with her family members, both in the werewolf pack and her biological family, in more depth.
One possible theme could be conflict. Since Bella lunged at Leah, there might be some sort of underlying tension or feud between them.
One common theme is self - discovery. Leah is often portrayed as trying to figure out who she is as a werewolf and as a person. Another theme is love and relationships. Since the Twilight series is full of complex relationships, Leah's fanfiction also explores her love interests, whether it's a new character or someone from the existing cast. And there's also the theme of acceptance, as she tries to be accepted by her pack, the Cullens or the human world.
I'm not sure of specific 'naruto and leah twilight fanfic' titles off the top of my head. However, when you search for it, pay attention to the ratings and reviews.

One common theme is redemption. Leah often has a journey of self - rediscovery and finding her place, and Paul can be a part of that journey. Another theme is the struggle with their wolf nature.

Leah, especially, is often on a journey of self - discovery in relation to Sam. And the theme of family also comes up as their relationships are intertwined with the larger werewolf family in the Twilight universe.
Power and identity are also prevalent themes. Leah's unique position as a female werewolf in the Twilight universe means her power and identity are often explored. Fanfictions may show her coming to terms with her power, or how her identity as a werewolf affects her relationships and her place in the world.
