It depends what your motivation is. I know some people who will use a taller tire all around to "fill the gaps" in the fenders. The 275/35 does a pretty decent job of that, but in turn, increases your rolling diameter, which is actually harder for the car to turn than a smaller diameter of the same weight. A taller sidewall, all things else equal, will give a cushier ride, but sacrifice a bit of turn in sharpness.

Pretty much this. If you wont even consider taking an eastwood roller (or baseball bat) to your fenders, the 245 will be your only option. Considering the OEM tire is of the same width, you have gained yourself essentially nothing in tire width, aside from a stretched tire

The only VMR i would consider is the 701 with 19x9.5 ET50 in the rear, and thats still barely a 255 tire for proper fitment.
