I think a father knows what to look for in a wife for his son. I think what he might not be sure of is the specific labels that seem to dominate frum life nowadays.
Because HaShem forbid that if you are a “Yeshivish But With It Hemishe” type family and you accidently indicate to the shadchan that you want a “Yeshivish Modern Kind Of Chasidish” daughter in law.
With the caste system that has been set up, it’s easy to accidently step down a rung in the social order. Hence the father trying to crowdsource the decision.
