Still, you're also probably overlooking how common sci-fi films are. Like say, Ad Astra with Brad Pitt (2019). The Martian in 2015. Blade Runner 2049. And so on.
Andor, Severance, and Devs come to mind, even though they're different types of thrillers to some extent.
Have heard good things about Station Eleven.
Even on Apple TV+ alone there are plenty to choose from, though funnily enough the one I've been watching the most is not the critically-acclaimed For All Mankind, but climate disaster drama Extrapolations: https://news.ycombinator.com/item?id=39543480
Fired on Mars on MAX is a gem of an existential sci-fi dry comedy.
Paper Girls on Amazon Prime has been cancelled, but it was a good time travel romp and comic book adaptation that wasn't a superhero one from the big two (it's an Image Comics title)
It's not quite the '90s extravaganza in terms of television sci-fi, but with all of the demand for streaming content, the odds are good, even if the goods are often odd. There's been like, three different Star Trek shows now, plus a cartoon. Surely there's something to be found from that.
First season of Altered Carbon was good. Also The Peripheral, albeit canceled before its time. Glad Gibson went with Apple to finally let someone take a crack at putting Neuromancer on screen; they're the only ones I'd trust not to cut it short too.
Still waiting for someone to put Daemon and Freedom(tm) on a screen of any size; that could get fun, but probably would need to be a series to avoid cutting out way too much.
This is my point. The last decade has been a sci-fi wasteland.
