The thing to keep in mind is that under the adventure styled bodywork, the NC750X is basically a street bike, and a good handling one at that. The 50 some horsepower is totally adequate for me, but the suspension and weight is not dual sport quality by any means.
With the right tires and some suspension mods, the NC maybe just might do what you want, but it will take some modifications. If you're in mud, I know from experience that it's easy to pack the close front fender of the NC full of mud, and stop forward motion.
If a DCT is important to you, then you're limited to the NC or the Africa Twin. DCT choices are limited; I don't think the heavier VFR or the Goldwing is what you're after.
I really believe Honda has a big hole in their product line. Honda needs a CRF designated mini Africa Twin with a manageable size and weight of something in the 500-600cc category. That's what I would want for the adventure riding you propose. I'd want a dual sport frame with the CB500 engine in it.
