Just something to keep in mind when deciding on tires - you have to run DSC completely off in order for this not to happen. Second - kind of constrained on widths & offsets on this platform. Just a bit of homework to do here - definitely workable solutions but the window is a bit on the smaller side to make it work here.
18 vs 19 - definitely more options in 18, imo the way to go if there is no brake clearance issues. Pricing is a bit better too - but having more options is the main benefit imo. Also want to consider tire progression - are you looking to get into faster tires in the future? If so then might not be a bad idea to make sure they are available to fit the wheel diameter & width you decide to go with.
Tire selection - besides the trades offs that you are already thinking about between the different choices - what are you looking to get out of your track time right now? Depending on what you are trying to do on track I think there are different benefits to each tire. RE71 is going to be the king for lap times in this range. From my experience RS4 as much as 4sec slower at a track like COTA - but the RS4 will last over twice as long. The NT01 is going to fall somewhere in between there while being extremely consistent down to the cords.
Also square is nice to increase lifespan. Staggered ultimately faster though if you take advantage of being able to run a bigger tire out back.

This is great
. Let me see if I can answer these in a concise manner.
Do you run DSC on or off
I ran all last weekend in Traction (Euro MDM) mostly to make sure I didn't do anything stupid but also because I was running those old Contis. I may transition to DSC off in December.
What are you looking to get out of your track time right now
Goals: I want to be in the high 2:30s and then progress to advanced group — I think this achievable with my current setup. But I also want to work on consistency, and having fun — even though I was struggling with grip, the car was a blast moving around a lot and staying relatively neutral.
