This video essay about the look of Sinners (which was shot on 70mm IMAX and Ultra Panavision) brought up something I hadn't realised until now: the large format gives you a wide field of view with the look of a telephoto lens! What that means is that you get shallow depth of field like in closeup shots with the framing of a wider angle lens.
Personal observation: there's also very little barrel lens distortion that usually comes with wide shots on 35mm.
