Actually is does matter, but not in the way you think. The engine could not care less at 4k miles which filter you use. But your wallet will really sit up and take notice. For 4k miles I'd run the least expensive filter and oil from any brand name or house brand you can find.
I ran SuperTech conventional lube for 10k miles on a Puro Classic filter and got outstanding protection. I can assure you that your use of your minivan is no more severe that the total soccer-mom short-hop driving my wife did for 19 years in our Villager. And that thing just keeps on running at 250k miles. Even after almost two decades of dino sauce in the crankcase and "normal" filters. And before anyone Yabuts me ("yeah, but ...") I can assure you the compression was great and the inside was very clean; I did regular cover-off inspections. It saw a life of 5k miles dino runs and some experimental long OCIs (10k and 15k miles) as it aged. And never a problem. Much of that is due to a good design, but you cannot discount the success of the "normal" products in my application.
Unless your engine has a propensity to sludge up, there is no real issue I can think of that would warrant the use of syn or premium filters at 4k miles. Grab some SuperTech conventional juice and a PC filter and be done with it. You're still probably wasting produt, but at least you can minimize the waste.
