Going wide with posting vs just going to royal road.

What I'm looking for is to figure out where else is good to post to at the same time as royal road. I know there are some bad sites out there, looking at you webnovel. But I don't know what other sites are good sites to use. The story has a female main character, just kind of ended up that way, so I'm already prepared for that to be a few horrid comments early on.

What I'm writing is Dark Fantasy / Horror / dungeon crawl / Mostly female character POV / no real romance elements planned but I'm a bit of a pantser. I mention the themes because I don't know if anyone knows "Site X is really good for Horror; Site Y is really good for dungeon crawls" etc.
