No.
Two reasons I can say that authoritatively: firstly, some bamboo is intended to spread and create a forest, but in other cases a bunching variety that is easier to restrain will be called for. Secondly, each variety has its own schedule for producing seed. A given variety goes to seed and dies all at once, worldwide; it's handy to have another variety established when that happens to your favorite, as a way to fill the gap.
Aside from that, I expect there is a harsh tradeoff between lumber quality and palatability. I bet there are other, less-steep tradeoffs regarding tillering vs. culm diameter etc., along which you can probably find a generalist species.
