Pretty cool. But, that might be overkill for a commuter bike but it is an option.

Being in Minne-flat-opolis a single speed was plenty for me for year but now I run a 1x8 Afline IGH year round on my commuter as my old knee joints prefer a few gear options. I use a 42t ring on the inside of a road double crankset with a bash guard on the outer ring for a bit of pants protection. A 1x set up has never been easier to get into considering whats available these days. you have a lot of options and can get a pretty wide gear range.
