It’s probably best to get acquainted with the Shapeoko while NOT also taking the steep Fusion360 learning path, Carbide Create and Carbide Motion are excellent tools for new Shapeoko users.
This being said, I have enjoyed the Fusion360 CAM tutorials from Autodesk, but they do require watching long videos.
The video series that really kickstarted my interest in using Fusion360 is that one, but it’s about the CAD part, which you already know.
And while I probably shouldn’t post a link to the competition, this intro to Fusion360 CAM sounds like a good way to spend 12 minutes to have an overview of the CAM module for casual CNCing.
