have less probability of overpenetration?
I don't think it would make much difference. The greater weight will increase penetration, and the slower speed will reduce penetration.
The actual degree of penetration will depend on additional design factors besides just weight and speed.
Any reasonable .44 hollowpoint should perform well. But not necessarily any better or worse than a reasonable .357 hollowpoint.

of .44 hollowpointed slugs, it was my choice to purchase
a bullet configuration of singularly W - I - D - E cavities in the slug,
to promote expansion. Comment on that strategy ?
Whether that would promote expansion would depend on how the bullet was designed.
Assuming you are buying a mainstream fighting bullet from a reputable manufacturer, it should expand as intended.
But another mainstream fighting bullet from a reputable manufacturer, that didn't have a wide cavity, would likely also perform well.
Large hollowpoint cavities in a large caliber revolver do offer increased possibility of warding off an attack without shooting though. If you brandish your gun at someone at close range, they will likely notice the size of the bullets/cavities, which will then inspire in them a desire to avoid being shot with those bullets.
OmSigDAVID wrote:3. Presumably, STOPPING POWER will benefit from
a greater hydrostatic shock, occasioned by a wider wound channel. Agree ?
Yes. But that is not the only way to increase hydrostatic shock. Having the hollowpoint expand much more explosively because the bullet is going much faster also increases hydrostatic shock.
