It really depends on the context. In terms of raw physical strength, Naruto has his super - powered ninja skills and access to the Nine - Tails' chakra which gives him incredible power. However, Ruby Rose has her speed and agility along with her powerful scythe, Crescent Rose. If it's a long - distance battle, Ruby might have the upper hand with her ranged attacks using Crescent Rose. But in close - combat, Naruto's hand - to - hand combat skills and ninjutsu could be dominant.
One common theme is the clash of cultures. Naruto's world has its own set of values and traditions, and Ruby Rose comes from a very different background. Another theme could be the exploration of their powers. How would Ruby's scythe - wielding and semblance work in the Naruto universe? And how would Naruto's jutsu compare? Friendship is also a likely theme as they are both characters who value their friends deeply.

There could be. A lot of fanfiction writers like to create crossovers between different universes. Naruto is from the Naruto anime/manga world and Ruby Rose is from RWBY. Some writers might be intrigued by the idea of a relationship between them and write fanfics about it. But it might not be as common as more mainstream crossovers within the same genre.
One possible fanfiction could be Ruby going on a solo adventure with Crescent Rose. She might find herself in a strange land where Crescent Rose's abilities are enhanced in an unexpected way.
