I missed your post. Sorry.
‘Plus, she being born in the US, and Cruz being born abroad, the case just doesn’t apply to him.’
Let me see if I understand this correctly, in other words, ‘Cruz not being eligible is not a violation of her rights.’
Is that the point?
Minor was a citizen. Her issue was not whether she was a citizen. Her issue was whether citizenship always includes the right to vote.
Cruz is a citizen. Cruz's issue is not whether he is a citizen. The question of Cruz's eligibility can be resolved by finding him to be a citizen via naturalization.
Two different people, both citizens, each having a different constitutional issue.
His case and her case have things in common (both are citizens), but the issue is different between them.
Cruz being ineligible does not turn him into an alien.
