Well, in a lot of Petunia and Harry fanfictions, an alteration can be how their pasts are connected. Some fanfics might explore if Petunia had some sort of latent magical ability that she hid, and this could change how she views Harry's magic. It could also lead to her teaching Harry things about magic that she learned in her own way. Regarding Harry, his view of the Muggle world through Petunia could be different. He might come to understand and appreciate the Muggle side of his family more deeply, which is a big alteration from the original story where he was often at odds with the Dursleys.
They can make the plot more complex. If Petunia is suddenly nicer to Harry, it changes the dynamic at the Dursleys' house. Harry might not be as eager to leave for Hogwarts, or he could have a different attitude towards Muggles in general. For example, if Petunia helps him with his magic studies secretly, he could be more advanced when he gets to Hogwarts, which would change his interactions with classmates and teachers.
