I would say Fantasy I include science fiction in fantasy as most scifi is not in the realms of possibility ie Fantasy. Some people like to lord over the fact about others reading about dragons and vampires but it's no different than reading about aliens that look like cows or look exactly like humans but different colour.
Divide Fantasy into genres then I like Space Operas, Urban Fantasy, Military sci fi, scifi Mysteries I have come to realise its the writing style of Authors I like more than the genre. So if I like an author I probably read everything they have written in all genres unless its smut I try to avoid that I have nothing against smut but I read to see new worlds and stories but smut takes my mind to the gutter
and out of the story.
For non fiction I mostly read about current tech or current affairs in short form ie online articles and stories rarely in long form such as books etc.
