Already been discussed here for hsl color picker

Color picker in HSL adjustment in PL

Maybe someone else has already mentioned this but in addition to available color swatches on the HSL panel an eye-dropper tool to pick the precise color you want to adjust would be nice. On one of my older cameras the blue represented in a sky that is too close to the sun comes out looking all electric and needs to be corrected. A color picker here would zero in on the problem straight away.

For adjustment you can turn them on/off in adjustment palette or other adjustment has a switch beside their name as you mention, having a shortcut key won’t really make a difference imo.
