One common theme is family conflict. Since Cedrella is from the Black family which has certain expectations and the Weasleys have their own values, there's often a clash between the two families in the fanfics.
Another theme is the exploration of their individual characters. Fanfics often dig deep into what makes Cedrella and Septimus who they are. How Cedrella's Black heritage has shaped her and how Septimus' Weasley traits influence their relationship is something that's frequently explored in these fanfictions.
Love against all odds is also a prevalent theme. Their relationship might not be approved by everyone, so the stories often revolve around how they fight for their love. For example, in many fanfictions, Cedrella has to stand up to her overbearing Black family members to be with Septimus.
There's a fanfic called 'Cedrella's Choice' which focuses on Cedrella's perspective in her relationship with Septimus. It shows her inner turmoil and how she overcomes family expectations to be with him. It's a really engaging read as it gives a lot of depth to her character.
