Each race has different starting attributes. But when you equip a class, those attributes are revised based on the class. Because Archer uses Dex as its primary stat for determining damage, and it doesn't need much Intelligence, your stats will be revised when you switch to Archer so that you get a buff to Dex and fewer Int points. If you switch to Paladin, you'll get more points in Vitality, and fewer in Intelligence.

Highlander Hyurs generally have higher Strength and lower Dex than miquote. So a Highlander Hyur on any job will probably end up with slightly higher Str and lower Dex than a miquote on the same class.
