Since you persist, I've googled pictures of her, and the answer is, in fact, most of the above. Her eyes, her skin tones, her hair color and texture, her mouth, her bone structure.
Now I'm not going to argue the point any further. You want to point out that other ethnicities, including Caucasians, might have her features, I'm tired of arguing. Maybe I just made a really lucky guess.
I'm guessing Sam Jackson is black, too.
Lynda Carter is Hispanic. She doesn't definitively look like it, and even if she did, that can work for Wonder Woman. Alba looks definitely Hispanic. Sorry if that annoys you for some reason.
What annoys meis ignorance and stubborn persistent ignorance annoys me even more. Here's my last clue for you: Many hispanics are Caucasians. So the "Hispanic" features you've spotted in Alba are Caucasian features. Hispanic means from or related to Spain. Hispanics ( as you pointed out) can be 100% European in ancestry, 100% Indian, 100% African or mix of any of those. All that is need to make them Hispanic is a cultural or linguistic tie to the Iberian Penninsula.
There are no anatomical or physiological factors in being Hispanic.
