Well, the theme of unity is quite big. Since the Reaper threat united many races during the war, in fanfictions they might continue to work together in ways they hadn't before. There's also the theme of lost knowledge. With so much destruction, a lot of knowledge was lost, and characters in fanfictions often search for it, whether it's ancient Prothean tech or cultural knowledge of other races. And, of course, the theme of new relationships. People who fought side by side might form new friendships or romances in the post - war world.
One popular theme is rebuilding. After the destruction of the Reaper War, characters often focus on rebuilding their civilizations, whether it's the Citadel races or those on the fringes.

Liara T'Soni can also be a great character to feature. Her knowledge of the Protheans could be crucial in a fanfiction. Maybe she discovers a hidden Prothean weapon that could turn the tide of the war against the Reapers.
