Nim as a language is a good place to go. The ecosystem is another story entirely. I suggest you search for the kinds of libraries you'd need and check their maintenance status, maybe do some example project to get a feel for the compiler and `nimble`.
Native Nim libs are definitely nicer, but being able to output C/C++/JS/LLVM-IR with nice FFI means you can access those ecosystems natively too.
It's one reason the language has been so great for me, as I can write shared Nim code that uses both C and JS libs (even Node) in the same project.
