To be clear, J-PAL addresses a variety of issues outside of poverty, and some are even fuzzy, like women’s empowerment.

I agree that inflation and unemployment are mutually exclusive when it comes to managing the central bank. However, is it really that much different from other problems with constraints? It’s not like an engineer just abandons a project and leave it up to ‘judgment’ - they find optimal ranges to adjust the dials to.

If your ultimate goal is to have more prosperity (in terms of employment and prices), the central bank is simply one of many tools that can affect this (and a pretty constrained one at that). You’d be better off looking at additional tools at your disposal, such as evidence-based vocational training programs, and scaling them nationwide.
