There's a great book on motivation that splits this differently:

1) realizing/seeing the impact of your work on real human beings

2) having objective metrics that you are influencing

3) being part of a team that treats you like a human and cares about you

The book is called "The Truth about Employee Engagement" by Patrick Lencioni

Your motivators feel much more accurate to me

That sounds suspiciously like autonomy, competence and relatedness from self-determination theory.
