One common theme is adventure. Since Jon Snow is often involved in various adventures in the ASOIAF universe, fanfictions usually include the reader character joining him on these quests. For example, they might go on a journey to fight the White Walkers or explore uncharted territories.
There's also 'Jon Snow and the Reader's Quest'. In this fanfiction, the reader gets involved in Jon Snow's journey and they face many challenges together. It's interesting because it shows how an ordinary person (the reader character) can influence the events in the ASOIAF world. The character development of both Jon Snow and the reader character is well - written.
One great 'asoiaf jon snow fanfic' is 'The North Remembers'. It delves deep into Jon Snow's journey after certain events in the books. It really captures his character well and the cold, harsh atmosphere of the North.

Well, in a Jon Snow x reader love story, it could start like this. The reader might be a new arrival at Castle Black. Jon Snow, being the dutiful man he is, is tasked with showing the reader around. At first, they just exchange polite words. But as time passes, they find themselves spending more time together. The reader starts to notice Jon's pain from his past, and Jon starts to find comfort in the reader's presence. One day, during a particularly dangerous night when the wildlings attack, the reader and Jon fight side by side, and that's when their feelings for each other truly start to surface. They realize that they have something special and their love story begins from there.
Jon Snow could potentially have allies like the Mormonts. They have always been loyal to the Starks. Maybe even some of the Dornish houses might side with him. They have their own reasons to oppose the current power structure in Westeros. And of course, his friends from the Night's Watch who left with him or believe in his cause could be his allies in this conquest. He might also gain the support of some of the maesters who see the value in his leadership for the future of Westeros.
Daenerys Targaryen could be one to help. Since she has experience with dragons, she could give Jon Snow advice on how to care for the egg and hatch it.
It could be a young and untainted Frey. Maybe a niece or a cousin of the more infamous Freys. One who has not been involved in the past atrocities committed by her family and has a more noble heart.
Daenerys Targaryen is often paired with Jon Snow in such fanfictions. Their combined power and the potential for a different kind of relationship makes it a popular choice among writers. Another character is Arya Stark. Their sibling bond can be explored in new ways when Jon is reincarnated, like Arya helping Jon with her assassin skills in a different plot line.
The North would surely support him. They have always seen him as one of their own and a great leader. Also, the wildlings might back him, considering he has a history of working with them and understanding their plight. Davos Seaworth would most likely be on his side as well, given his loyalty to Jon in the past.
