This is my subjective impression, not based on scientific sampling. Nonetheless, I think you should prefer cooked, hot food from a cuisine whose associated country already has had a traumatic experience with coronavirus. They will take the risk more seriously. You should avoid uncooked salads from lackadaisical countries that have been slow to respond.
In other words, I believe Chinese food is safest. Furthermore, entry restrictions have been on Chinese people for some time, so the chance that your cook or waiter picked up the coronavirus from China and is still carrying it is very small, whereas Italians have been free to come and go with no real questioning at the airport.
Chinese restaurants also tend to be in the suburbs, and they pack in the tables less closely.
