Given that he is related to Sam and Dean, fanfics often involve scenarios where he meets them in different ways, either through time - travel or some supernatural means. It's interesting to see how he interacts with his descendants and how they all deal with the family legacy together.
One common theme is exploring his past. Since he was from an earlier time in the Winchester family history, many fanfictions delve into his life before the events of the show, his relationships, and how he became the person we know a bit about in the series.
Love and relationships are also important themes. It could be the brotherly love between Sam and Dean, but sometimes fanfictions introduce romantic relationships for them as well. Also, there are often themes related to the consequences of their hunting lifestyle, like dealing with trauma, guilt, and trying to find a normal life outside of hunting.
One common theme is the female Winchester's struggle with the family legacy. Just like the male Winchesters, they have to deal with the supernatural world while also trying to uphold their family's name.
Well, the theme of protection is quite prevalent. The sister might be in a position where she needs to protect her brothers or vice versa. Also, there's the theme of identity. She could be trying to figure out who she is in relation to the Winchester legacy. For example, is she just a hunter like her brothers or does she have a different role? And then there's the theme of sacrifice. There are times when the sister has to make sacrifices for the greater good of the family or the world in these stories.
One common theme is adventure. Since 'Supernatural' is full of hunting monsters and going on quests, fanfictions often continue this trend with Amy Ray Winchester. She might be involved in hunting down a new, dangerous creature.
In fanfiction about Henry Abaddon's Daughter in Supernatural, a frequent theme is identity. She has to figure out who she is in relation to her father. Family drama is also common. Maybe she has a conflicted relationship with other family members who are also part of the Supernatural world. And love can be a theme too. She could fall in love with a character from the show, which would add an interesting dynamic to the story.
One common theme is adventure.

People like to pair the characters up in different ways, creating unique love stories between Stiles and an OC Winchester.
One common theme is the bond between Dean and Sam. When Dean is kidnapped, Sam's determination to save him is always a central part. It shows the depth of their brotherly love. Another theme is the exploration of Dean's vulnerability. Usually, he's seen as strong, but when kidnapped, his weaknesses are exposed. For example, in some fics, he has to face his fears of being alone or tortured.
One common theme is 'forbidden love'. Since Sam has his hunter duties, a relationship with an OC can be seen as something that goes against the rules of his world. Another theme is 'finding strength in each other'. The OC often brings out a different side of Sam, and they help each other grow and face challenges.
The theme of redemption is also present. The OC may have made mistakes in their past, and through their adventures with the Winchesters, they seek to redeem themselves. This could be related to accidentally causing harm in the supernatural world or having a dark past that they are trying to overcome.
In Adam Winchester fanfiction, the theme of belonging is quite common. He has to struggle to belong to the Winchester family, which has its own set of rules and relationships.
