Door jamb wider than framed entry
I could give you some easy tips on adjusting the door and jamb but I would only do that if there wasn't the option to - make the frame bigger (rough opening).

You can plane off 1/4" on one of the sides in about 5-10 minutes and you won't be messing with the integrity of the door you bought.   You can plane sloppy and with shims you are still good to go.
