Well, many Sasuke and Itachi fanfictions focus on their family history. How their clan's past influenced their relationship is a big part. Additionally, there are those that center around their individual quests for power and how that affects their bond. Some also explore the idea of forgiveness, as Sasuke has to come to terms with Itachi's actions, which were full of secrecy and complexity.
One common theme is the exploration of their brotherly love. It could be about Sasuke finally understanding Itachi's sacrifices for him. Another theme is their power and how they compare to each other in terms of ninja abilities. Also, the theme of redemption might be present, especially in relation to Itachi's actions.
