Maybe other members will also add a few lines to this tutorial. It would be fine to get information how people doing their scenes.
We are all using our characters in a specific scene, but lighting a scene in an effective way can be very hard ... I often try to get the answers from real photographers and then hope, that it also works in Blender.
To start with, I often had a problem lighting my models from the front. Two lights left and right create weird reflections in the eyes (very light edges). One light from the front creates white circle in the mid of the eyes, but it also make the face look very flat. Then I discovered the ring lights, sometimes used as a real ring, sometimes used as an effect with a number of light sources instead of one ring. Here is an example from the real world:

or in this video for one of the most professional models ...

The eyes of the model should directly look into the camera, because the ring light should reflect in the eyes only. So I created a ring light and did this setup:
The result, done with filmic log encoding base in Blender using cycles and base contrast, looks like this:
