I'd say Rust's knowledge will be more valuable in comparison. You can work in Blockchain development, compile to WASM (WebAssembly). There is a new JavaScript/TypeScript runtime named Deno (by the creator of Node.js) that has its backend in Rust.
FastAPI is modern microframework. If you haven't used any of them, I'd suggest FastAPI. Django REST is also good if you have previous experience with it.
