One common theme is the blend of magic and non - magic elements. Since Jacob is a Muggle and Queenie is a witch, their married life often involves showing how magic can be integrated into an ordinary life. For example, Queenie might use magic to clean the house while Jacob bakes in the kitchen.
There's also 'Queenie and Jacob's New Beginning'. In this fanfiction, they get married in a small, intimate ceremony. It focuses on how they deal with the reactions of their respective families and friends. Queenie's sisters are initially a bit worried, but Jacob's charm wins them over. It also delves into how they start a business together, with Jacob's baking skills and Queenie's magic helping to attract customers.
A common theme is the exploration of their unique bond. Since they come from different supernatural backgrounds, the fanfiction often shows how they make their relationship work despite the differences. Another theme could be family. They might face issues related to starting a family of their own or dealing with their extended families. For example, how Jacob's werewolf pack accepts Nessie and vice versa.
One common theme is the overcoming of their initial rivalry. In the original story, they are sort of enemies, so in fanfictions where they get married, there's often a story about how they put aside their differences.
In this fanfiction plot, Queenie and Jacob find out about the pregnancy early on. They are both thrilled but soon realize they need to deal with many practical issues. Jacob has to figure out how to balance his work at the bakery with taking care of Queenie. Queenie has to deal with her own magical issues during pregnancy. They also start to think about the future of their child in a world that is not always accepting. They face family drama as well, with some of Queenie's wizarding family being less than thrilled about Jacob being involved.
Here's a short fanfiction idea. Queenie discovers she's pregnant one morning. She tells Jacob, and he is initially speechless with happiness. As the pregnancy progresses, they find out the baby has some unique magical abilities that seem to be a blend of both their natures. They decide to keep this a secret for a while. Queenie uses her magic to create a special nursery, while Jacob works extra hard at his bakery to save up for the baby's future. Their love for each other and the unborn baby grows stronger every day.
Another theme is growth. As they are both young in the story, fanfictions often show how they grow both individually and as a couple. For example, they might learn how to deal with their unique powers and how that affects their relationship.
One common theme is unrequited love. In many fanfictions, Jacob's love for Bella is often not fully reciprocated in the way he hopes, leading to a lot of angst. For example, in some stories, Bella is still torn between Jacob and Edward, which creates a lot of emotional turmoil for Jacob.
One common theme is Jacob's struggle with his identity. As a werewolf in the Twilight series, he has to deal with his dual nature, and many fanfictions expand on this internal conflict.

A major theme is loyalty. Jacob is extremely loyal to Nessie, and this is shown in many fanfictions. They also often explore the theme of family.

Additionally, the theme of power is there as Nessie has unique powers that she has to learn to control, with Jacob sometimes being involved in that process.
