The fish in Japan is excellent but much of it isn't native. It comes from somewhere else, frequently the Gulf of Alaska, the product of which is available fresh in Seattle without sitting on a boat for a trans-Pacific journey. Asia pays top dollar for it though, so they get a lot of it. But here? It is where they got it from, it is big business. The quality of sushi in Seattle is somewhat famous, not only the myriad local sources but its direct access to the entire Pacific Rim.
I wouldn't have to go out of my way to find good cheese in many parts of the US. It isn't the 1980s, the median availability is similar to the median availability in most of Europe, here in 2022. You seem to be fencing with stereotypes instead of reality. I don't have a dog in this fight but (1) I spend a lot of time, and have spent a lot of time, all over the world and (2) I eat absolutely everything everywhere and in particular investigate their food markets. I'm not guessing about what is and isn't available to the average person in various places, I actually shop in those markets.
Every place has their local specialties, and some places in Europe really do go above and beyond, like northern Spain. But the quality and availability has radically converged in my lifetime for everyone. Americans are not benighted or some such, their markets are quite good this days. The fact that ordinary suburban US supermarkets routinely carry hundreds of cheeses from all over the world is quite a change from decades ago. The actual cheese shops just specialize in obscure cheeses that minimally intersect with the ones the supermarkets carry.
All that aside, Americans have amazing produce. That and beef are two things they do exceptionally well by any standard. I've never been able to get anything comparable in Europe.
