Seems solid enough of an outline. My only note is I highly recommend git first, you don’t need to be an expert or anything but if you understand the basics and use it you will never lose a line of code and be able to lookup historical changes to find issues faster. Then when ready you can stand up a simple git server like gitea to host those repos and collaborate.
Yea, I did. When you start modifying configs and writing shell scripts git can help you track those as well.
