You might try some of Azimovs short stories. For a bit more meat you might try Frederik Pohls Hee Chee saga. Book 1 was great.
Not really sci-fi, but shirt and very good: Fictions/Ficciones and Labyrinths by Jorge Luis Borges. Also, Invisible Cities by Italo Calvino.
Something not by one of the more well known authors I could recommend are the Indranan War trilogy and Farian War trilogy, by K. B. Wagers
Also, The Frontiers Saga series by Ryk Brown is fantastic, and I think getting close to 40 books by now
Daemon by Daniel Suarez. I read that as a young programmer and it’s still in my mind. Written before the whole AI hype.
The godfather. People always say the book was better. This is the case here
Haven’t seen this one mentioned, but The Three-Body Problem by Liu Cixin might work. I don’t believe there’s a lot of first person, but it’s an interesting read.
Naive Super. Not sci-fi, but a quick enjoyable read. I've read it 4 times now. Its just a fantastic simple book to get back into reading fiction.
There are some great suggestions here - I'm also adding to my reading list!
I almost exclusively read sci-fi, and my favourite author is Peter F. Hamilton. He has written some mind-bendingly good space opera, much of it spanning multiple novels.
His best work IMHO is a one-shot, standalone novel called Fallen Dragon. It's got rampant uber-captialism, space marines, geurilla warfare on colony worlds, and aliens. And a very satisfying conclusion that I didn't see coming.
Read Everworld
Roadside Picnic. Not too long, but phenomenal overall and told via first person.
John Scalzi's book are an easy read. Its a lightweight Sci fi though.
Old Man's War, and Starter Villain are the two of his books I've read and enjoyed.
