Thanks for this. I think this is the route I’m going to take. I eventually want to move to a full SSG but need a midpoint before then. I just want my files in markdown to start with.
Np! Some additional info -- the site I mentioned, I also installed/configured the PicoEdit plugin for them so they can use a fully web-based interface to create/update content. They've been very happy with this process and were glad to move away from creating raw HTML files and FTP'ing them in. For non-tech users, it's a lot easier to use a CMS system like that instead of SSG and git workflows. (Netlify CMS could help with that workflow, but I have to play with it more to learn about its quirks)
