I don't know it was explained in the series or in interview with Kubo, but most soul reaper or strong soul reaper are they are who born as a soul, that's very rare case of dead human to have spiritual energy to become soul reaper, just like in Renji and Rukia back story, most of dead human who become soul don't feel hungry while Renji and Rukia feel hungry meaning they need source for their spiritual power. more powerful your soul you gonna feel more hungry just like in Toshiro and Momo back story, Toshiro need to eat watermelon a lot, so I think it's safe to assume that every soul reaper that live on Soul Society are born soul unless they tell us their back story
