There are things like Picard and his Dixon Hill adventures, Data and Sherlock Holmes, Janeway and her gothic romance holonovel, those give a fairly diverse selection of tastes too. Sure, Dixon Hill and Holmes are both detectives, but there's a big difference in the style. Beverly was big on amateur theater. Miles and Bashir liked playing darts, and trains too I think, and all kinds of silly boyish hobbies. And there's regular poker games and gambling at Quark's.
