...I'm pretty sure if you presented a list of these traits to 1000 people probably 999 of them will recognise and identify with them.
Yes, you're right! And some people show a trait at some times, not in all situations. But I think it's not so much the objective assessment whether or not we have a certain personality trait, but how thinking about the given trait affects us. For instance, I didn't believe I was a goodist (always striving to please others ahead of myself). If you asked me, I could find lots of people around me who are goodists, starting with my parents, siblings, ex partners, i.e. people close to me who must have influenced my perception of myself. In comparison, I thought of myself as a very selfish person, and when someone disliked me I would assume this selfishness as the reason. Which bothered me of course, but what can I do, I'm just not "goodist-enough"?! Not good enough, not likeable, non-lovable...
Well, living with such feeling of inadequacy and constantly beating myself over not being goodist must have its consequences. Looking objectively - I am a goodist, at least I tried to be but it didn't make me any more popular, only got taken advantage of. But my subconscious still believes I should be. The same with perfectionism - the world pushes everyone in this direction: only perfect is good enough. I recognize I'm not perfect, but then I'm insecure at work and in relationships. Or try telling someone that you accept yourself despite some weaknesses - they'll judge you as lazy, not even trying any self-work.
I suggest we should really look at how we FEEL about the various emotional traits. Not asking "do I have it?" but "if I have it or don't have it - am I still OK?" What are we resisting, e.g. "I never want to be a perfectionist like my father". See all that leads to inner conflict - lots of emotional buildup, and eventually physical tension.
