If want to check if a person record has email addresses. So:

ABMultiValueRef emailMultiValue = ABRecordCopyValue(person, kABPersonEmailProperty);

If the record has no email addresses, do I get a NULL value in emailMultiValue, or some other special CFTypeRef value?

You do not get NULL value cause of kABPersonEmailProperty record returns multi value type.
Actually it returns valid object with empty list of values:
NSLog(@"%@", emailMultiValue) -> ABMultiValueRef 0x156bbb00 with 0 value(s)
