I'm not sure what your use case is that only rust and gonare options, but is unusual. NIM supports concurrency and is as portable as the c and js it can generate to. C#/F# work on x86 and arm which covers most targets today. And supports concurrency. And is situationally more performant than go. I can't speak to the other languages mentioned, but they all seem quite similar to go as well, except for haskell. Rust is more like c, c++, zig, ada etc.
