"incentivize higher wages in a way that set rates make producers more profitable if they paid workers more"

You can just put in the trade agreement that the goods are subject to tariffs unless the workers who made them are paid enough. The USMCA, for example, has requirements along these lines for auto assembly (https://www.dol.gov/agencies/whd/usmca).
