The real question in my mind is the prevalence of Long COVID and other longer lasting changes. Having seen the debilitating effects of post-viral fatigue syndrome (non-COVID, but still very similar) I would caution everyone to do as much as possible to avoid getting illnesses that are known to trigger extended disability like this.
A COVID infection isn't a binary outcome of live or die. There's a lot of potential for lasting damage that isn't fully studied yet, so we need to stop treating the statistics as a simple matter of life or death.
It's also misleading to consider the statistics for children in isolation because children obviously don't live alone in isolation. If kids get a contagious illness, the parents are highly likely to get it. This is especially true for younger children, as any parent will tell you.
