Deutsch: "US-Amerikaner" Español: "Estadounidense" Italiano: "Statunitensi" ...
so there are plenty of languages that do make a distinction between "American living on the American continent(s)" and "American from the US". Full disclosure: I'm from Germany...
"Americano" is used too, as well as "afroamericano" (not "afroestadounidense").
What I really want to contribute here though is that your "we" from "what we call ourselves" doesn't include me. Like a lot of people outside the US, English is my native language and calling Americans Americans has always given me pause for thought. So I put it back to you:
Is it even possible for us to be wrong about what we call you?
In general, these kinds of errors come from historical limitations: orthography, linguistics, &c. At minimum, it’s respectful to try to adapt based on our better, contemporary understanding.
