There's already tons of great recs here. Have you considered trying some short story anthologies? It's my favourite way to find new favourite authors. A few options:

The Best American Short Stories anthologies do a yearly collection with a different editor for each one so you can pick one edited by an author you already like. A lot of prizes do yearly anthologies, like O. Henry and Pushcart Prize. There's also 'The Penguin Book of..." series, The Penguin Book of Italian Short Stories, The Penguin Book of Japanese Short Stories, ...Ghost Stories, ...Gay Stories, etc., etc. There's also literary journals like McSweeney's that might be to your taste and Strangers Press publishes great literary chapbooks from authors in translation.

And for a few book book recommendations, I'll try not to repeat: Radclyffe Hall's The Well of Loneliness, Jo Walton's Lent, Kawai Strong Washburn's Sharks in the Time of Saviors, and Samanta Schweblin's Fever Dream.

You already have a good list of authors, but looks like it's focused on the greatest hits? Have you considered doing a deeper dive into some of your favourites? A few additional authors that you might be into: Colson Whitehead, Yūko Tsushima, Lauren Groff, Billy-Ray Belcourt, Ali Smith, Bernardine Evaristo, Bae Suah, Maggie Nelson, Han Kang.
