ESTA, national identity card for travel by any other country?

I suspect that the other answer is correct, but if it isn't, and you follow its advice, you could be found permanently inadmissible to the US for misrepresentation. The chance of that happening is perhaps small, but the severity of the consequence could be very significant.

Therefore, unless you can establish definitively that the cédula for a non citizen is indeed beyond the scope of the question, you may want to play it safe. To elaborate on the analysis in my comment, there are four possible circumstances deriving from these two questions:

1. Is the cédula within the scope of the question?
2. Did you disclose the cédula in response to the question?

The four circumstances are:

1. The US doesn't care about the cédula and you don't disclose it. Here, there is no problem.

2. The US doesn't care about the cédula and you do disclose it. Here, there is also no problem.

3. The US does care about the cédula and you do disclose it. Here, there is still no problem.

4. The US does care about the cédula, but you don't disclose it. Here, there could be a problem.

You have no control over the first question, but you have complete control of the second. So it is entirely within your power either to rule out options 2 and 3 or to rule out options 1 and 4. Since the only negative option is 4, you want to rule out options 1 and 4, and you do that by disclosing the cédula on your application.

This analysis could change if there were a possible negative consequence of disclosing the cédula, but nothing you have said gives any reason to think that is the case.

Although it doesn't say, they're interested in national ID cards for travel issued by your country of citizenship, not alien residency cards.

So you aren't supposed to fill the details in of the one you have.
