Looks amazing! Great setup.Just made this choice myself (P6GR ten spokes). Ended up landing on 20" due to the lack of tire options for 19".
Specifically, I wanted Michelin PS4S tires with a 35 sidewall. Only options for 19s were 295/35/19 (too skinny on the 11" wheel IMO), and 305/30/19 (305 would have been fine, but again, wanted the taller sidewall).
Setup I went with was 20x10/11. 275/35/20 Front, 315/35/20 Rear. Zero regrets, looks and drives amazing. Pic below, 1" lower front and back.

That's true, but some are interested in keeping the overall tire diameter closer to stock so it doesn't impact the speedo so much and make the car accelerate slower. A 315/35r20 tire is more than 1 inch taller than most stock setups. But it does look good the way it fills the wheel gap, and it allows you to run at stock ride height or slightly higher with lowering springs installed.
Can't have everything. Stick with a 19 inch wheel.That's true, but some are interested in keeping the overall tire diameter closer to stock so it doesn't impact the speedo so much and make the car accelerate slower.

Lucky for me, the tune programming tool that came with my Whipple kit allowed me to program in the different tire size. I would assume there would be similar programmers you could buy (or borrow from a shop) to do the same.That's true, but some are interested in keeping the overall tire diameter closer to stock so it doesn't impact the speedo so much and make the car accelerate slower.

I would expect any aftermarket tuner can make the adjustment. Pretty sure it's doable with forscan, too.
305 35 20 fits fine on the back with 1" lowering springs. I just ordered 315 35 20 nt555r2 and I may have to adjust the rear cradle a little bit. It's not perfectly centered, even with the Steeda alignment kit. This is a common issue on S550s. My 15 had the same issue.That's true, but some are interested in keeping the overall tire diameter closer to stock so it doesn't impact the speedo so much and make the car accelerate slower.

20s are fine.
