I like to increase the saturation a little bit to vivid the colours of the landscape, plants/flowers or clothes. But doing this with a (caucasian) human in the photo quickly makes the skin too pink.

Is there any easy technique to increase the saturation except for the skin tones?
I have more or less zero knowledge with the tones and HSV tools.

The red band is also highly influential, but orange will have the most impact on skin tones. If orange adjustments don't do much to skin tones, it probably means your CT is set to a lower value than your light source's output, your magenta ←→ green setting is too far into magenta, or your light source has a low CRI. \$\endgroup\$

Anything wrong with checking the "Protect skin-tones" box in the "Vibrance" section in the "Color" tab? That's where I'd raise saturation normally.

In Photoshop, by placing a hue and saturation adjustment layer, the change can be global (Master) throughout the image or by color by choosing it from the master dropdown menu. Adobe Photoshop Hue/Saturation adjustment layer

Starting from this image, the image on the left is the original, and the one on the right is the retouching only increasing the saturation of yellows(minimally), greens, cyans, and blues:
