(The titles listed below are BOOKS of short stories, rather than individual titles.)
I recommend ANYTHING by
Flannery O'Connor.
Or, if you want something that skirts genre and literary, try
Shirley Jackson's short stories.
For pure, unadulterated Literature (with a capital 'L'), try this author:
John Cheever.

If you find dead white guys problematic, then I highly recommend
The Stories of Eva Luna, by
Isabel Allende. Literature of the highest order!
https://www.amazon.com/Stories-Eva-L...s%2C220&sr=8-1
I find all four writers to be wonderful !!!!
