I conscript the entire fort. I just hate dealing with worn clothing, so I put everyone in a squad, hand them some leather crap that counts as armour, a crossbow, and mention that the monthly goblin shoot takes place on level 13.
However, I soon become dissatisfied with the leather crap. So by this stage, with 120+ dwarves, I decide that everyone is getting steel gauntlets, helms, and mail shirts. Every time.
This takes years and years of dwarf time, HUGE amounts of very valuable resources and results in my entire fort dropping their gauntlets and running around to pick up someone else's everytime a new masterwork set is made (not to mention all my dwarves being seriously slow due to wearing steel without any armour user skill), but goddamn it's cool to be able to look at any dwarf's inventory and see a full set of steel armour. Also cool is seeing your dwarves bravely stand their gorund when they encounter the goblin ambush, sometimes even surviving long enough for the military to arrive.
That's another thing: I never build vast surface forts that control the entire flow of traffic over the surface. I'll make a small motte-and-bailey type thing, or a walled tower or something, that sits in the centre of the map, so that my hunters, fishers, and gathers really are braving the wilderness, and I never just seal up the fort until the enemy goes away or sit behind rows and rows of traps. My dwarves die fight with courage.
Also, since everyone is in the military, I seperate people into squads based on profession, with everyone in the squad having the same job set. So there's the haulers, the labourers, the masons, etc. People are never shifted between squads, unless it's from a civilian squad to a pure military squad.
And, needless to say, everything has to be masterwork. I always set up vast furnace floors with a huge stockpile for any non-masterwork metal stuff. Half my haulers are always busy hauling goblinite or similar, and I often have a full ten dwarves in my furnace operators' squad.
Any artifact armour I give to my commander/militia captains, any artifact anything else I make sure is placed in its creator's bedroom.
I've gotten over my multi-z everything obsession though, despite the reduction in beauty, and I've also moved away from the 7x7 rooms.
