Actually, I think that maybe racial and cultural differences might also factor in: a race that's better piloting smaller ships will probably have fleets dedicated to small ships, with probably even no ships larger than a cruiser; a large race, or an aquatic race, might require more space, so they may end up making ships bigger than the ones the Eteno use(d?); flying races that have great maneuverability in the air may be more prone to using fighters, due to similar maneuverability, and therefore probably have predominantly carriers.

Not just the military aspects of a race's military: sometimes, you gotta see the cultural or racial aspects as well.
