Eugenia Uniflora [Also called 'Surinam Cherry'] is a sub-tropical plant and many people treat them as tropicals and overwinter them indoors [Your call, I don't think I would subject it to your winters by any means.]
I am unaware of the benefits of dormancy vs overwintering indoors for these as I don't grow them.
I do often see them sold as 'indoor bonsai'...

Which Zone do you refer to? Sunset Or [url=https://www.usna.usda.gov/Hardzone/hzm-sm1.html]USDA[/url]
USDA says 'Zone 5' [A or B] Temps = -10 to -20F for Colorado & this is not going to make your cherry very happy.
Sunset ZONE 5. =
Ocean-influenced Northwest Coast and Puget Sound
Growing season: mid-April to Nov., typically with cool temperatures throughout. Less rain falls here than in Zone 4; winter lows range from 28 degrees to 1 degree F/-2 degrees to -17 degrees C. This "English garden" climate is ideal for rhododendrons and many rock garden plants.
That doesn't sound like Colorado to me...lol
BTW - https://davesgarden.com/guides/pf/go/57945/ Says they will tolerate near freezing but this is for established IN GROUND trees.
