If you want to do a really comprehensive tutorial, I would suggest a tutorial on a Gibson ES-335 guitar because it is the most complex. Carve top solid bodies and even all acoustic arch-tops would be less complicated and would use a subset of the techniques for the big Gibson.
To do an ES-335 you need to carve both inside and out, top and bottom, f-holes, a center block that matches the contours of the inside of both the top and bottom, a mortise and tenon neck joint, a scarf joint or v-joint at the headstock, a full sized heel, a neck volute (for the scarf joint), a neck, compound radius fingerboard, fretslots, and even a tailpiece (if you want to go fancy ala Benedetto).
You would be my hero if you did a tutorial that went from CAD (my vote is for Rhino) to finished milled pieces ready for assembly. I was working on these steps and then lost access to the CNC machine before I had a chance to implement them

Still on the fence about trying to build my own. Until then the project has been stalled for me.
