I really enjoyed the Edward Herrman narration of the "At the Mountains of Madness" when I listened to it years ago.

What struck me is how it still feels haunting even decades later; it aged quite well. I couldn't help shake the creepy feeling there was something unearthly at the edges of our world.

I really enjoyed listening to the Silo series by Hugh Howey recently. I also went through a Stephen King binge years ago and I specifically recall Frank Muller did a great job with the narration on many of the books (sadly he passed away before finishing the Dark Tower series).

For cosmic horror “a colder war” by Charlie stross is great.

The Bobiverse series is a top notch sci-fi audiobook with great narration. https://audiobookdb.net/series/3B5S2xAj

or if you want a single audiobook you have to listen to Project Hail Mary from the author of the Martian https://audiobookdb.net/audiobooks/Vg0f71nk

hope you enjoy these
