First, know your source materials well. You need to understand the lore of the Sith from Star Wars, as well as the other universe you're crossing over with. For example, if it's with Harry Potter, know how magic works in both. Then, create a strong plot. Maybe the Sith are searching for a powerful artifact in Hogwarts. And don't forget to develop your characters. The Sith should have their own motives and personalities that are consistent with their Star Wars roots.

One possible fanfiction could be about a Sith Lord from Star Wars ending up in the Naruto universe.

First, develop a unique Sith character. Give them motives that are not entirely evil, like a Sith who wants to reform the Sith Order from within. Then, focus on the character's backstory. Maybe they had a rough childhood that led them to the Sith but also instilled some good values. Next, create interesting relationships. They could have a friendship with a Jedi who challenges their beliefs. Also, use vivid descriptions of the Star Wars universe, like the dark, brooding Sith temples or the bustling Jedi academies.
How about a plot where the Sith OC has a connection to one of the main RWBY villains? Maybe they are related or have a pact. They work together to bring chaos to the RWBY world, but as the story progresses, the Sith OC starts to have second thoughts. They might start to see the value in the RWBY characters' way of life and have to decide whether to continue down the Sith path or turn against their villainous ally. This would create a lot of drama and character development within the fanfiction.
Avoid the 'instantly redeemed' trope. A Sith turning good overnight without proper development is unrealistic. Also, don't use the 'chosen one' trope too much. Just because they're a good guy Sith doesn't mean they have to be the only one who can save the galaxy. Another trope to avoid is the 'evil for the sake of evil' in the other Sith characters. Make their motives more complex.
