I've been deploying Rust to AWS Lambdas for months for a side project. I chose rust because it's just my favorite language to work in - I'm very productive in it. I also really wanted predictable, solid performance, and Rust is a great fit for that.

I don't really like any of the 3 languages you mentioned though.

How are you wrapping your Rust code? Lambda doesn't support it yet, does it?

Many use the Go runtime, which doesn’t care what kind of binary you actually use. There’s tooling to support this too.

aaaaaaaaaaaaaand today they announced support!

If you had to pick a fourth language what would it be?

I honestly don't know. I primarily work in Python professionally. Java before that. I guess of that list C# seems the most tolerable but I have the least experience with it.
