That is quite an angle you are describing, forcing you to roll your thumb under your palm exactly like Apple says you shouldn't do in its Mac Ergonomics document.

Resting your pinky naturally on control is quite easy because as it turns out, your fingers are not of equal length. So if you put your hand down on the keyboard in its most relaxed, natural position, most of your fingers may end up on the middle row and a shift. From there you only need to slide your relaxed hand downwards to get it in the perfect position for a ctrl-c/v action: Pinky on control, index finger on the x/c/v.
