Imo you’re approaching horror wrong, horror as a Genre has more lineage out of decadent and symbolist and ultimately romantic lit than people give it credit, many of the great horror writers aren’t writing to scare you but instead are trying to create a very ornate supernatural aesthetic, the middle ground is ghost story writers who were based in the concept of the ghost story yes, but often wanted to fill it with a scholarly aura, a very ivory tower nature. That’s not just weird fiction dudes but the top guys in ghost story writing like MR James.
With this in mind I think you’d find much of value in the short fiction of Blackwood, Mr James, Gilchrist, la fanu, of course Poe, Machen and Ambrose Bierce. You’ll definitely find excellent writing.
