I use SD exclusively for APA and IPA. In my experience, its just chico but faster and maybe attenuates a little more. This is to say that it doesn't accentuate malt flavor much, and most beers I make with it are very hop forward.
Have you considered Omega's Gulo? Its a cross between irish ale yeast and french saison yeast, but lacks the phenolic/fruity character of the saison parent. Its like irish ale yeast but STA+ so it will attenuate super well. I've used it for porters, dry stouts and also pale ales. If you ferment it warm enough (80s) you will get a little bit of peachy notes out of it, but its pretty clean otherwise. It might work nicely for what you're going for.
