Ray Nayler: The Mountain in the Sea (Hardcover, 2022, MCD) 4 stars

Humankind discovers intelligent life in an octopus species with its own language and culture, and …

many intelligences

4 stars

Impressed by how many types of intelligence and consciousness are woven together in this book. I count at least 9; some characters embody multiple kinds in ways that become clear.

One thread seemed less necessary, and another one was very grim, but worth the payoff. And this is the only cyberpunk cryptid first contact SF I can think of.
