I think it comes down to your needs. Maybe the answer is you don't have any needs and this is just a want... either way, here are a couple thoughts.
If you were thinking of flipping it, building it stock would be the most economical build and resale would be better for stock than something crazy (with respect to number of potential customers). Single cab is not as desirable most places. I don't know about in CA.
I don't know if you will have problems registering it if you do the PSD swap or not. It is technically legal to do that swap by EPA because that engine came in that generation truck. Again if re-saling that might be a negative but having a PSD truck might bring more money.
A clean cab with title is usually something that someone somewhere needs. That's a harder sale I would guess out there than it is out here so parting it may or may not get you the best bang for the buck.
At the end of the day, I think it depends mostly on how big a project you want to tackle because honestly, all of the options you presented are projects... even parting/scrapping takes some level of effort.

the neighbors were all multimillionaires, and they did not like me much...
