A fanfiction could focus on Sakura and Syaoran's daily life after the main events of Cardcaptor Sakura. Maybe they are training new cardcaptors. They could be facing challenges like how to teach the newbies about the importance of the cards and the right way to use their magic, all while their relationship continues to develop in this new phase of their lives.
Adventure is also quite common. Fans like to write about Syaoran going on different adventures, either related to collecting cards or something completely new. Growth as a character is another theme. Fanfictions often show Syaoran growing, becoming more powerful, and maturing both in his magic skills and in his relationships.
Love is a very common theme. Since they have a special connection in the original series, fanfictions often explore the growth of their love. Another theme is adventure. They are both involved in magic, so new adventures are often written about. For example, they might go on a quest to find a lost Clow Card.
One interesting fanfiction could be about Sakura and Syaoran going on a new adventure together in a parallel world. They might face new Clow Cards or some other magical threats. In this story, their relationship could grow even deeper as they rely on each other to overcome difficulties.

And 'The Magical Bond of Syaoran and Sakura' could show their bond growing even stronger as they face challenges that test not only their magic but also their relationship.
Perhaps in the fanfiction, there's a parallel universe where Sakura and Syaoran are enemies. They have to figure out what has gone wrong and how to set things right. This would involve a lot of self - discovery and exploring the nature of their relationship in different circumstances. They would need to find a way to break the spell or whatever is causing this rift between them and restore their normal relationship in their own universe.
