Hot vs cold oil changes

unless the engine oil is REALLY sludged up (no one on this board runs oil that long I hope), the only difference in draining 'hot' vs 'cold' is the time it takes to empty the pan. Modern oils keep ALL the crud in suspension. Your engine would not live more than a few minutes during a cold start otherwise.

by 'cold' , I mean above 40F.

The small amount of oil left in the pan is of no significance. Far more important is using good fuel, good filters, and good oil changed 3-4K miles in normal stop and go, more often in very dusty or cold or short trip service.
