Op, either sand will be just as strong at the same mix ratio. However, building sand is more workable, easier to use, won't slump, and so is the one to use.

No it won't. A larger aggregate requires less cement to get the same compressive strength, as there is less surface area to the same volume of material.
So for the same mix, sharp sand will give a higher compressive strength.
Neither should slump as they should be mixed semi dry so that it is less likely to contract and crack.
Anyway, doesn't really matter as either will be fine at 3:1.

Yes, as we both know, sharp sand has larger grains than building sand. Even the fact that the sand is sharper will make for a stronger mix than rounder grains, all else being equal.
