I do believe these 'issues' are quite the same

They're not. The centrifugal pump efficiency curve maximizes at a particular flow rate, usually around 2/3 the max (not scientific, just guessing from the charts I remember). Maximum pump efficiency is not maximum or minimum of either flow resistance or flow rate.
As far as just the water part is concerned, the aim should be to maximize flow for a particular arrangement of blocks and radiators. The efficiency of the pump should make no difference unless you have a pump drawing close to an amp and dumping almost as much heat into the fluid as the CPU.
The end goal, I imagine, is to find the particular arrangement of pump, block, and rad with the lowest delta-T.
