Is there anything to gain from a larger unit crew (column O)? I can only think of downsides like more pressure on manpower, higher costs with it and maybe more casualties taken. Would an APC with 11 men (crew plus soldiers carried) in game have any advantage over one that has 7 for example just because of this value?
AFAIK your assessment is correct. The stat is primarily used to promote realistic manpower usage for real units. For example many UAVs have 0 personnel and other than their horrible stats in comparison to manned units they function just as well. (but need no reserve personell to man so thats primarily their main advantage, the smallest of nations with the smallest of reserves could build a mighty UAV airforce if so inclined.)
