There are two issues: dep bloat and “hermeticity” if you will. Cargo is quite nice and projects build in a straight forward way. However, the Rust ecosystem sucks in terms of dep bloat, imo. And the compiler artifacts are large. Python not sure, but I thought you had a way to get hermetic environments?

Go stands out as being fast, small and very limited dep bloat, thanks to a comprehensive standard library. And very minimal config files. By that standard npm is a shit show.
