I personally don’t care for CC, but a lot of readers do and if you don’t offer it, most it your fanmail will be full of people asking for it (that’s exactly what happened to me in my first story).
In my current story, I allow the readers to fully CC the MC and two LIs, but I make it very clear I use a lot of hand and arm overlays. I make my overlays in three different shades per character, and highlight the shades that match. I find this gives the readers a wider range of CC options, while still allowing me the freedom in my directing I’m looking for. I always choose a light, medium, and dark shade each so that even if the readers don’t pick one of my recommended skin tones, hopefully the one they pick will be close enough to the three on the side to not ruin the reading experience. You could always do three different skin tones and let the readers pick from only those three if you wanted to be exact.
