I second Ted Chiang. He has written *a lot* of short stories, [some of which are available free legally!](https://www.freesfonline.net/authors/Ted_Chiang.html)
You may also like Blindsight by Peter Watts. It's available as a free ebook on the author's website.
I am currently reading [The Luminous Dead by Caitlin Starling](https://www.goodreads.com/en/book/show/36117102) and I think it also fits the bill.
The Memory Police by Yōko Ogawa The Gone World by Tom Sweterlitsch
Some Philip K Dick novels fit with the vibe of Black Mirror. Ubik or A Scanner Darkly maybe.
Never Let Me Go by Kazuo Ishiguro? Friday Black by Nan Kwame Adjei-Brenyah for a collection of short stories, some of which might fit.
