Is there a definitive list of intrinsic motivators?
While I wouldn't and cannot claim anything conclusive about intrinsic motivation, as far as I know, Self-Determination Theory (SDT, see below) is quite accredited. In short, at its core it postulates that humans are motivated by three innate psychological needs: Autonomy, competence, and relatedness. 

Moreover, I believe that the motivating factors listed in the question can be reduced to the three needs postulated by SDT.
