I have an SN2700 in my rack, next to a pair of Arista 7060CXs (as a point of comparison). These are wildly under-rated devices outside of the STH fanbase.

You may be surprised at how quiet and low power these Mellanox switches can be.

Quiet in the terms of DC grade switching, I'm not sure you could get away with such a switch in a home environment. The 100G optics need plenty of airflow to keep cool so it's not just a case of swapping the fans for something smaller

The rack I’m referring to is in my home. YMMV, of course.

You can use a 100g DAC within a single rack (which is also cheaper). I only have a tiny bit of 100g at home and just do 10g optics for the connection out of the rack. Of course, that's my weird setup and it won't work once I want 100g to my office.
