Yes I prefer to use distinct names for ethnicity and nationality as well. That is why if you look at the Vietnam and Japan infoboxes, I used Kinh instead of Vietnamese and Yamato instead of Japanese although this practice isn't as common. I wasn't aware (or forgot) that the Greek ethnicity could also be called Hellenes, but I will change it to that right away. I will refrain from changing Egyptian to Copt though because I fear that will cause confusion since Copt nowadays is almost always used to refer to the ethnoreligious group. Moreover, the ethnic field is meant to cover major ethnic groups throughout the civilization's history, not necessarily something rested in the modern demographics; I'm not confident that in the context of Ptolemaic Egypt, copt was used for ethnic Egyptians then. I don't know when the term first arose. As well, in modern times many Egyptian Muslims still identify as ethnically Egyptian not Arab but not as Copt.
This example aside, I agree we should try to use a different name when one exists.
