Go is definitely a decent solution but I'm surprised why you aren't using Python. Most Linux and BSD distros have access to a default install of Python. Even if the version is a bit old, if all you're doing is hydrating templated configuration and doing bookkeeping for eventually running a binary with some parameters, older versions of the standard library will do just fine.
Not gonna lie, I have a certain prejudice against Python because of the whole packaging issue, something I definitely need to work on. I did ship Python code before, I just don't really like using it.
I do have the pyinfra documentation saved so I remember to take a look at it. I love Go for many reasons, but the distribution of binaries is probably at the top.
