While very much a beginner here......I would take the path I followed.Build a kit guitar first.That way you have a little experience sanding,finishing,assembling,wiring and setting up an instrument.You would be surprised how much you can learn from the experience....unless of course you have already put together a few kits.
It took me a few over the years,but I finally got a great result so I am going to challenge myself to build closer to scratch.Good Luck!!!
