What type of non-fiction are you reading? You can probably find a fiction book that’s in the same style.
Eg. If you’ve read autobiographies you can find similar first person novels. If your reading history books then you can find similarly styled books.
Both fiction and nonfiction are very large genres with many sub-genres, most people are going to like one of these sub-genres.
Also note that fiction isn’t all fantasy, I’m sure you know this but there are many books which have no distinction from non fiction except that they didn’t happen.
