Fit's A/C blows cool, cold, cool, cold...

In many cases cars do have variable displacement compressors.

However, most of them still need to cycle on and off anyway.

I know this for a fact, as my 2003 Saturn ION and Dad's 2007 Pontiac G6 had variable displacement compressors that would cycle off and on based on the temperature of the car interior.

I found (generally speaking) that most Japanese makes have compressors that only cycle on/off, the cold/cool you are experiencing is only something I have found in Toyota, Honda and Mazda. My other half had a 2012 Scion TC that was one of the worst offenders at letting the air get muggy and warm during the off cycles even when it was nearly brand new, you could clearly tell when the compressor was taking a break in that car. My Mazda 3's were better at keeping the muggy cycle to a minimum but they still had the temperature and humidity swings but to a much lesser degree.

I never understood the benefit of variable displacement compressors until I actually drove and lived with cars that have them (Volkswagen). You don't get the constant driveline jerkiness of a compressor cycling on and off nor do you get the cool/cold cycles that come along with an on/off compressor. Except for my '99 Dodge Neon which could cause an interior polar vortex within its interior, nothing has compared to the A/C systems in my Volkswagen's and now my MB.
