if US that implies a specific company

You mean Consumer Reports?

Regarding the two sets of keyword phrases in a double size meta description, I think that would look a bit unnatural and neglects to focus on the most important function of a meta tag, which is to promote a clickthrough.

Those second and third string phrases are longgail. Longtail, by definition, is rare. So I'm not going to fret over those. One page can have hundreds of variants, more if it's a longer page. At that point you have to let it go and worry about the bigger phrases and how the associated meta descriptions will display for those bigger phrases in the SERPs.
