Ugh. CU doesn’t state that corporations are people. They can’t vote or own guns or get married or divorced. They can’t be legal guardians to children or pay income tax. They aren’t entitled to Social Security benefits and their coverage for health insurance may be denied for preexisting conditions. What CU said is that collectively people can use company resources to exercise their right to free speech and established the concept of super PACs.

This isn’t to say that it was the right decision (certainly seems to have done some very bad things). But “corporations are people” is a lay person talking point, not an actual legal doctrine. Therefore you can’t just apply it to other cases because there is nothing to apply.

You are correct that free speech isn’t limited by your citizenship status.
