I’m not sure how that’s the opposite of prioritizing, but if I’m wrong, then I’ll happily admit it.
We choose our items/workflows/technologies/whatever, so we get the best/most efficient/most effective/whatever, across the widest possible set.
Sounds like prioritizing, to me, but I’m just a dumb hick, so I suppose I can be wrong.
Prioritising is when you choose something over another. A drag racer prioritises time to travel a quarter mile.
Going for the Pareto is when you elect not to prioritise. It is explicitly deciding to not choose one property over another ant to keep everything as much as you can.
