Fanfiction.net is another place to look. There are many Game of Thrones fanfictions there. However, the search might require a bit more effort as the site is quite large. But if you search specifically for Sansa and Loras marriage fanfiction, you should be able to find some.
I also like 'Sansa and Loras: A New Alliance'. In this fanfiction, their marriage is not just a union of two individuals but also a strategic move for their families. It goes into great detail about how they navigate the power struggles within the Seven Kingdoms while trying to develop their own relationship.
In the comics, Daredevil's marital status varies. But one notable character he marries is Elektra Natchios. However, the comic universe is complex, and there might be alternate story arcs with different spouses.
Thor's marital partner in the comics is not always consistent. Sometimes it's Jane Foster, and in other cases, it could be someone else. It really depends on the creative direction of the particular comic series.
