For total power dissipation calculations, don't forget to consider dissipation through the load. Here is an instructive presentation on the topic.
You are correct, however, in that the lower quiescent current part will generally consume the least amount of power. I would add that it looks like you've overestimated the OPA2348 quiescent current plot. The bottom line is the quiescent current plot (~42uA at 3.3V), not the top.
