I came up with film also. I remember reading about the characteristic curve of the films I was using. In general a properly exposed curve was mildly S shaped and they varied according to the steepness of the slope and where and how strongly the upper shoulder broke over and the same variation on the lower heel area. The steepness of the curve indicated the amount of contrast, and you could vary a little with push or pull processing, or by choosing the contrast grade of the printing paper later.
With digital the curve is at your disposal. You can set your own black point, white point, and middle point. You can go linear, mild S, strong S or any thing else. You can alter the slope by grabbing points in the curve and pulling up or down. Or you can click in the image and raise or lower the curve at exactly that point, sometimes with polarizing results. Luckily the undo or reset button is at hand.
Point being, you dial in your own curve, so as long as you don't blow out important highlights or lose shadows that you needed detail in, the exposure isn't as critical as film.
