One common theme is the exploration of hidden heritage. It often shows Harry finding out that he has a connection to Slytherin through his family tree. Another theme could be the struggle between the different values of Gryffindor (which Harry is known for) and Slytherin. For instance, Harry might have to reconcile his Gryffindor courage with Slytherin's cunning.
Well, power is a big theme. If Harry is related to Salazar Slytherin, he may inherit some powerful magic or abilities. Also, redemption can be a theme. Slytherin has a bit of a bad reputation in the original series, so fanfictions might explore Harry as a way to redeem the Slytherin name. And of course, there's the theme of identity. Harry has to figure out who he is now that this new aspect of his heritage has been revealed.
In these fanfictions, a common theme is the re - evaluation of the Hogwarts houses. If Harry is Salazar Slytherin, it challenges the traditional view of the houses being so separate. Another theme is the mystery aspect. How did this connection remain hidden for so long? Writers often explore this mystery. Additionally, there can be a theme of unity. Harry, with his newfound link to Slytherin, might try to bring the houses together more than in the original story, bridging the gap between Gryffindor and Slytherin.
