If you like grounded sci-fi that elicits a “it could happen in a few years” vibe firmly rooted on Earth, check out William Gibson. Most of his stuff is excellent, but “The Peripheral” and its followup “Agency” are recent highlights. From his older stuff I very much enjoyed “Virtual Light” the most. More than his acclaimed “Neuromancer” (he invented the word cyberspace in 1982 and popularized it in this 1984 novel) even.
Neal Stephenson - “Seveneves” One of my all time favorite sci-fi books. It is set mostly in space, but very realistic and never leaves the Earth’s influence. Time setting is basically now or a few years from now.
Also by Stevenson: “Anathem” Marvellous alternate universe story with a few twists. It’s on Earth, just … different.
If you wanna go for the classics (1960 roughly), look into Stanislaw Lem. “Solaris”, “Eden” and “Transfer” all left a lasting impression on me.

I survived on that stuff when I did a one week Kebdo training camp in Japan. It’s fantastic!
