Artists associated with the Age of Enlightenment rejected:

the Rococo focus on superficial beauty.

Explanation:

While Enlightmenet and Rococo both expressed liberal, new ideas and departments from the strict Church ideals, the artists and thinkers of the Enlightenment did not like the banality of rococo. The Rococo style was focused on fun, beauty, and opulence, often depicting wealth, playfulness, and hedonistic enjoyment in earthly goods.

Enlightenment, on the other hand, heavily criticized monarchy, valued the revolution and the perspective of the working class and the intellectuals. They were trying to be rational and political, so the artists would focus themselves on the philosophical and knowledgeable topics and their depiction in the art.

The artists and thinkers of this movement found Rococo to be indecent and superficial, too occupied with trivial enjoyments.
