How about two states? As mentioned above, Florida and California couldn't be further from each other in terms of policy and response, yet age-adjusted mortality was about the same.

That's pretty easy. Sweden is the poster child of a rational covid19 response.

Sweden deaths per million: 1834

U.S. deaths per million: 3043

However you can also choose various European countries that avoided masking children and minimized school disruption. France and UK for starters, but also all the Nordic countries. Sweden being quite different from the other Nordic countries, but all of them being consistent in avoiding school disruption or masking children.

Most of Europe does not recommend vaccinating young children either.

France deaths per million: 2242

Denmark deaths per million: 1122

Sweden had a higher death rate than its neighbours combined. Also just like Denmark no very large, densely populated cities.

Paris proper is 2mln people squeezed into a 100km^2 city. Greater Paris is 10mln at a definitely urban density. It's no wonder they had larger death rates and this is a apples to oranges comparison.

All the European countries that you listed have good public heath care systems, especially when compared with the US situation. That’s the main reason they had less deaths per capita, not their lockdown policies.

The UK absolutely required children to wear masks in schools in various situations. Schools were closed for significant periods of time as well.
