I've been using Ansible for years now to do this. Right now all my computers run fedora so there's not much difference between them but for some time I used Ansible on macOS too. It worked but was a pain to make my roles compatible for both linux and macOS. In my experience Ansible is good when dealing with text files or if there's already a module for what you're trying to do (for example managing postgresql users). If what you're trying to do is complex enough that you need to write a custom module or plugin, it is a pain in the ass: we had to do that at work and it was terrible. Ansible works on Windows but I have no experience with it.
