The best I've found is to calibrate the image, then sometimes add a bit of extra blue, reducing that orange look to skin tones. Depends on how the calibration looks, as to whether I'll adjust it further. I usually only add a bit of coolness to the image, not a ton. I find this gives a more neutral skin tone across a wider range of content, though it can make some content a tiny bit less saturated looking, but usually it's not noticeable as much as it reduces those orangish looking skin tones. Of course if you overdo it, then it will look way too clinical.
