I tend to spread no-quality jobs among a great number of dwarfs, to ensure the job just gets done when it's needed. Thus, i have no specialist soapmakers, beekeepers, butchers or cheesemakers (since i just bulk-order 'shear animal - spin thread - milk animal - make cheese', sometimes with a plant processing job thrown in for good measure, every dwarf intended for farmer workshop use gets those five jobs all enabled). I appreciate the work of my soapmakers, but usually there's not a dwarf who is _the_ soapmaker.
I have a soft spot for dwarfs who did something notable for their fellows - the furnace operator who was the only one willing to regularly work in the hospital, who in spite of a total lack of skill managed to get a dwarf with a broken skull back on its feet. The pair of starting miners who bravely chased a couple of Draltha all across the fort and finally back out to the caverns, while suffering no serious injury - one became my military commander, the other my duchess.
I also tend to pay special attention to dwarfs who got severely hurt, trying to better their lot - my most vivid memory is of a dwarf child who got paralysed from the waist down when a magma crab entered the fort through the improperly plugged magma workshop. He was reduced to crawling around forever, but i set up a workshop specified for him, with a stockpiles of rope reeds and whip vine and a bedroom nearby, and let him work his way up to legendary thresher over a couple of years. Out of curiosity, i then switched off his labours and stuck a dwarf girl of similar age into his bedroom. It took about seven years, but the two eventually married and started to make babies.
