Yes, I thoroughly enjoy short stories, for all the reasons that you give.
I grew up on the classic fantasy tales: Conan, Fafhred and the Grey Mouser, the Dying Earth tales, and all of Dunsany, Clarke Ashton Smith etc etc as well as Lovecraft, Poe and M R James and the rest.
As well as focusing on a single mood or concept, as you suggest, short stories - particularly the more literary ones - are great as single character studies, or dealing with particular interactions in a way that isolates and brings them to the forefront simply by being given a beginning and end.

Personally, I always used to carry a paperback with me and would read in the odd moments that this writer seems to recall as being so dull and soul destroying. I still do carry e-books on my phone of course and use them in exactly the same way - but also with the option of doomscrolling, of course.
As for TV, I was never one for TV - or radio - as background noise. With fiends, I had a bit of reputation of going round and turning such things off when I entered the room, so that we could talk without distraction. I would ask them first, of course.
