Exurb1a is also worth reading. He's better known for his YouTube video essays (which vary between bleak and profound, usually within the same video), but he has published several books. I got about halfway through Fifth Science before leaving it on a plane (yesterday); I plan to rebuy it so that I can finish it.
In the sci-fi space I'd argue that Ursula K. Le Guin is another must read. She was heavily influenced by taoism (and eastern philosophy). When you approach her work with that in mind, it adds a whole new layer of depth to everything.
I’ve never encountered anything like Egan before. I’ve heard Stanislaw Lem mentioned in conversations about him though. But I can’t vouch for the comparison myself as I’ve never read Lem.
Both are fresh voices and well worth reading, but I don't think Lem comes anywhere near Egan's diamond-hard sci-fi. Egan knows, and does, real math; you can sometimes find him at the n-category Café. My impression is that Lem's beautiful philosophical ideas were not accompanied by comparable math or physics knowledge.
Lem is humanist. The sci-fi part is only a vehicle to make you think (eh, if you want to), and while things are written in 1950-80... they are not outdated, because humans are essentially same, for millenias. Just read "Stories of commandor Pirx". Somewhere in the middle of them, you may notice something like the current frenzy around LLMs and ethics. But he goes further..
The last time I responded to a similar comment by suggesting asking an AI, I was downvoted to hell. I won't do it again. I will note, though, that the list generated was excellent and provided rewarding information.
