Hello Chris, based on your old blog I had developed macro suite for the developers in my org to interact with SharePoint back in 2022. here is the code base. It's very comprehensive and can interact with SharePoint files, folders, and lists. I also resolved the greater than 200MB limitation with Graph API. Check it out if you have time and please drop in a comment.
