Redemption is also a popular theme. Since Regulus had a turn towards the good side in the end, fics often explore how he might have redeemed himself further and how Sirius would have reacted to that. Some stories show them reconciling and working together against Voldemort.

This can create a sense of mystery and suspense in the fanfiction. Another theme is the power of choice.

I recommend 'Regulus and Sirius: A Forbidden Bond'. This fanfic beautifully portrays the complex emotions between the two brothers. It shows how their different paths in life affected their bond. There are some really heart - wrenching scenes that make it a must - read for fans of the Blacks.
Fanfiction about these three can take many forms. For example, there could be time - travel fics where Harry goes back in time and meets Regulus and Sirius when they were younger. This could lead to all sorts of interesting plot twists, like Harry trying to prevent Regulus from joining the Death Eaters in the first place. Or it could be a fic where Sirius survives and he and Harry explore the secrets of the Black family together, including things that Regulus left behind. There are also fics that focus on the emotional bonds between the characters, showing how the different personalities of Regulus, Sirius, and Harry interact and influence each other.
Isolation is another theme. Given his situation, Regulus often finds himself alone. He can't fully trust his family, and he's also involved in dangerous and secretive activities. This sense of being alone in his struggles is often explored in 'Regulus Black Hurt' fanfiction. It's like he's in a bubble of his own pain, cut off from the world around him.
