You would be fine with the full syn. The most important part is how you break it in and how fast you change the oil. Warm it up and then give it hell through the rpm range. Change the oil and filter within an hour. Change again in about five hours and then to normal schedule.
Did you remember to check your ring gap?

I plan to use 0W-50 Mobil 1 racing oil that is doped too heavy to run in anything with a CAT. Plus it is a close match weight wise to the Polaris 2W-50 that comes in new engines from the factory. Low quality machined parts might do better with dino for break in but for the rest synthetic is the norm today it seems to me.

The current P4 oil is 5w-50. I'd run a non synthetic as close to that as you can for the first couple hours. Then again at 5-10 depending on your use. Then regular changes after that with full synthetic.

When did they change it from 2W-50? Until last week I was thinking it was still 0
w-40.

Not sure. My 12 850 manual says 2W-50, but the stuff I've been getting from the dealer for the last year is 5w-50. They changed from 0w-40 some time before last year. It's all confusing!!!

About half way in they give the new grade...

??Why not?? What makes you think dino oil is superior for break in? They come from the factory with full synthetic and it seems to work just fine.
