I really like 'A New Dawn for Jacob and Rosalie' in the world of jacob black and rosalie hale fanfiction. It starts with a very interesting premise where Jacob and Rosalie are forced to work together on a mission that could save their respective clans. As they spend more time together, their relationship evolves in a very engaging way. There's also 'Moonlit Meetings' which is full of intense emotions and great character development for both of them.
One common theme is the exploration of their relationship in an alternative universe. Since they are from different 'sides' in the Twilight series, fanfics often create scenarios where they can interact more freely.
One interesting fanfiction could be about Jacob and Rosalie forming an unlikely alliance to protect the Cullen family from a new threat. They put aside their differences and use their unique abilities to fend off the danger.
Jacob's family might be initially shocked, especially if it was unexpected. But they would likely come around and be supportive. His parents might offer their wisdom on raising a child. Rosalie's family, depending on their nature in the fanfiction, could be either overjoyed or a bit more reserved. If they are more traditional, they might have concerns about the relationship between Jacob and Rosalie.
Perhaps a plot where Jacob and Rosalie are forced to go on a journey together. During this journey, they face various challenges that test their limits. They might have to rely on each other's unique abilities to survive. For instance, Rosalie's super strength and speed could help in some situations, while Jacob's ability to transform into a wolf gives them an edge in others. Along the way, they develop a friendship that was unthinkable at the start.
Their relationship could start off rocky. Jacob has always had a bit of a temper, and Rosalie is not one to back down easily. But as they interact more, they might find common ground. Maybe it begins with a grudging respect for each other's loyalty to their own kind. As time passes, they could start to see the good in each other beyond their species differences. For example, Jacob might admire Rosalie's fierce protectiveness of her family, and Rosalie could come to appreciate Jacob's straightforwardness.

A fanfiction could be set in an alternate universe where Jacob and Rosalie are both students in a prestigious art school. Jacob is into more rugged and earthy forms of art, while Rosalie is drawn to the refined and classical styles. Their clash of artistic visions at first leads to rivalry, but eventually they inspire each other to create new and unique art forms.
They could start by having common goals. For example, both might be interested in protecting a certain human from the darker elements of the supernatural world. This shared objective can bring them together and make them interact more, gradually building a relationship.
