Introverts have a lot of inner tension. ... Extroverts have way more inner peace.

I've found the opposite. Introverts are happy to be by themselves not because they need to sort them selves out but because they are at peace with their own company. Extroverts on the other hand constantly seem to need to work something out about themselves or the world around them and can only do so by bouncing the ideas off others. Many times the other person isn't even necessary more than a prop. I've had many conversations with extroverts where all I've added was "aha" and "OK" for 30 minutes while they basically monologued, only to have the other person thank me for the insightful conversation and claiming I really helped them out.

"Sorting themselves out" is a loaded word, I see that now.

I agree with you. This being at peace with your own company is a result of a tendency to work on your inside, and respond to emotions and "calls" from there immediately.

The other side are people who regularly experience a state of mind which could be described as happily relaxed nothingness. No thoughts, ideas, inner monologues etc. No urgency to work on their inner life.

That isn't better or worse. It brings advantages and disadvantages.
