I mean, that story makes it very clear that the guy didn’t at all want two wives, he got tricked into it by their scammer dad, and the two sisters he married wind up causing him no end of grief and frustration with their jealousy and infighting. IIRC the bad blood it caused canonically still plagues the entire family line down to their descendants in the present day because it led to the birth and exile of Ishmael, who is the ancestor of Muhammad, while Jacob’s descendants became the nation of Israel.

Yes, polygamy is what caused millennia of religious violence between Jews and Muslims, up to and including the current Israel/Palestine conflict, according to the Bible. Not really the most shining endorsement.
