At my workplace we're using Go with Lambda and Fargate for several mid-size and one large application. The costs (image storage, transfer ...) you're referring to are actually almost neglectable. Aurora is by far the largest in our stack.
On the other hand: Creating WASM is a big pain. I understand that Cloudflare and others promote it for their own business reasons, but from a developer/customer point of view docker or lambda are much more robust and simple.
