When it comes to white balancing landscape photography I think a colorchecker is next to useless.
The concept of a colorchecker is to make colors look the same under any light. But in landscape photography you often shoot in extreme light (sunset, dusk etc) for which the eye/brain does not fully compensate for. Daylight white balance and profile will often give a more natural look for evening shoots than some special made evening profile.
Scenes with snow and late light here in the north is a very clear example of this. You can't just white balance for the snow or something, because it does not look white in that extreme light.
The best solution I've come across is to be a lot in nature, get a feeling for the light and colors, use a calibrated screen, use a daylight profile, and pull the temperature and tint sliders manually until it looks good and natural according to your own color memory and judgement. Actually, leaving at the default daylight white balance often leads to a good result. There are no tools available to make something "accurate", ie same as the eye/brain experience the colors at the scene, in these light conditions.
Color checker workflows are for 5000K type of color temperatures.
White balance from LCC shot I've tried briefly, haven't been able to produce sane results with it. It has the same problem... in extreme light white is not really experienced as white, and it's also a bit subject dependent.
Attached and example, late light in Abisko in January, tuned manually to replicate the eye's experience at the scene. Colorchecker or LCC shot would make no use there, other than showing that the light temperature is far out of bounds :-)
