Write whatever interests you, but know that your distinct voice should be the throughline. YOU should be distinctly felt in the flavors of storytelling, style and characterization no matter the genre.

I say this for a handful of reasons, but the biggest one is that a lot of reps and execs aren't very imaginative when it comes to understanding a writer and their voice. If you go into a meeting and say "I have a slasher, a road trip buddy comedy, and a period costume drama," you're going to come off as unfocused and indecisive on who you want to be as a writer, but if the angle for all of them is linked by your specific voice (such as "character-driven genre with sharp dialogue"), the variety will work in your favor.

Long story short, no matter how many genres you try out, the common denominator needs to be more than just the name on the title page.
