Hypercapnia will only happen if you have some kind of underlying condition, like COPD. It primarily becomes an issue with particulate respirators like N95s, where it really does add airway resistance and guarantees extra airway dead space.
Surgical asks do reduce spread of particulate spray if coughing a lot, and it has been shown to reduce transmission of pathogens from yourself to other people. That being said, the CDC is telling the general public NOT to wear them. They only want cloth.
You're generally correct. It's not a good filter for small micron sizes, but it reduces the dispersion by physically slowing down an aerosolized spray that has been accelerated by a cough or sneeze. Basically, it catches larger droplets and slows down the smaller sized particles. Instead of having a large radius of suspended particles, it's more confined around the source.
It's a marginal benefit at best for a virus, especially in close quarters with fans circulating air within the room.

Not entirely correct. It does reduce initial dispersion of aerosolizing spray like when you cough or sneeze.
