When the principle that embracing essential anxiety is the highest form of knowledge conflicts with the principle that physical health enhances social stability through cognitive resources and self-efficacy, which principle should take priority?

I think that if one's mental health is in a good state, the former should be prioritized, and otherwise the latter. The former has a strong character of intellectual luxury that can only be embodied once anxiety has been resolved to some degree, so under ordinary conditions it seems better to first recover a healthy mind and body.
