The whole trip is misguided given both your preferences and time of year. Wolf Creek is the only one of these places with a good early season snow record. If you want to do this trip, do it for your spring break, not in December/January. All of these places are very high altitude, mostly north-facing, so well suited to spring break.
With regards to the specific areas:
Wolf Creek: Best snow, mostly intermediate but short runs under 1,000 vertical
Santa Fe: Decent balance of terrain, but not a huge area, 1,300 vertical
Monarch: In the same class overall as Wolf Creek and Santa Fe for terrain and vertical.
Purgatory: Mostly intermediate, bigger than Santa Fe or Wolf Creek, about 2,000 vertical, steep sections are short.
Telluride: The area you will like best IMHO. Historically it's been stratified for terrain, but expansions and grooming have greatly improved its intermediate appeal. When they groom Bushwacker or Plunge, those are ideal GPaul runs of 2,000 vertical.
Crested Butte: Famed mainly for its extreme terrain (half the acreage) which is not likely open until mid-January or later. The Muellers may tout the quality of the grooming but the variety of intermediate runs is low relative to most Colorado areas.
Taos: Similarly 50+% expert weighted like Crested Butte and similarly likely not much of that terrain open before mid-January. I like the fall lines of Taos' groomers on Chairs 7&8 better than Crested Butte's. Taos also has the famous ski school that might help expand your horizons beyond the groomers.
