I regularly feel "wiped out" from a typical cold, often for 4+ days in a row.

This whole thread is full of anecdotes from people implicitly claiming that their experience applies to everyone, when in reality everyone's going to have different experiences with everything from colds to covid. Unfortunately, the latter has a much higher prevalence of seriously-worse side-effects (long-haul, ageusia, anosmia, death, etc) compared to the former.
