I once tried a pork chop for this and it was dry and bland, maybe because there's not enough fat in this cut?

What are you making? The cut depends on knowing if you need a fattier or leaner cut.

I would go with shoulder, also known as boston butt.
Go with pork butt ... All the way

Definitely shoulder (aka pork butt). You need the fat for flavor and moisture.

You'll need a pork shoulder. Best ratio of lean to fat for ground pork.
I always use Boston butt/shoulder roast. Using tenderloin doesn't have enough fat. Usually around 20% fat for ground meat is about the right proportion.
