I am not a big fan of it either, but I see a non-zero chance that same brains with simpler environments can sometimes ponder or experiment with some problems more.
If you believe that your rain dance has to please the rain god, you won't optimize your rain dance for muscle building or other physical benefits.
It will also be less effective for other people who copy the rain dance without believing in it's significance.
Now, as for sports, just from the top of my mind, competitive acrobatic dancing e.g. womens pole dancing would easily satisfy a large chunk of it. This is why I think there is a potential to optimize it.
Pole dancing isn't ergonomic. It's bad for joints. It doesn't train good movement habits.
If you want acrobatic dancing there's Zouk. Outside of regulated ballroom dances that have rules about feet touching the ground stage dancing also involves a lot of acrobatics.
From your list of goals I don't think "Feeling proud" is a worthwhile goal. It's better than feeling angry but I don't consider it to a clearly positive emotion.

It does not differ too much from standard gymnastics, rings, bars, horse, vault etc. And while I am not sure what makes movement habits good or bad, to me gymnasts look like the kind of people who have perfected the mastery over the body.

Healthy level of self-confidence then. "Nerdy" people tend to have far lower than what is healthy. Social anxiety etc.
