If you are more focused on the devops part, and not implementing a static site generator, then go with Python. For our static sites we use Hugo + GH Actions + Kubernetes (since we have a cluster anyway). There is not really any code involved here (example: https://github.com/hofstadter-io/cuetorials.com)

I'm personally interested to try https://docs.dagger.io/sdk/python/ for something. I used the CUE sdk, but it is effectively deprecated at this point. I use a mix of base, make, python, and CUE fro most devops / devex stuff now. Dagger makes it so local & CI stuff runs the same.
