I've run 5w30 and now running 0w40 in my 508 0w20 required VW. My oil change interval is more often than what is recommended.
Other than internet hogwash, there hasn't been any 'engine design' that prevents using different grade of oil, albeit with uncommon sense....don't use a 25w60 during winter when driving around the north pole. I only know of one automaker that programs failure with the wrong grade of oil, wrong ATF.... and I don't own or would even consider their garbage products.
I drive my VW 10k miles a year, give or take a couple thousand, and change the oil twice a year, giving me grade choices for my spring/summer oil vs the fall/winter oil, every 6 months. Clean oil is important to reducing deposits.
With your intended interval, ANY full synthetic 0w20 or 5w30 could be used. And, I'd consider seasonal grade changes.
Don't wait for your 1st oil change. Don't wait for your 1st ATF change.
So, 500-1000 miles on the 1st oil change is a good starting point, and maybe 25-30k for the ATF/diff/coolant/brakefluid/.....
Run a yearly IVD cleaning spray and don't worry about carbon deposits. Your more frequent oil change interval should reduce the buildup, regardless of the oil grade.
I'd love to see 508, C20, and SP/GF6 battle it over engine protection and deposits.
Which one that could be better is unknown.

Location shows winters(Illinois? ). Since you keep your cars until the wheels fall off, maintain it and consider 5w30 for spring and the 0w20 for fall. And, looks like there is room for a bigger 7317 filter in place of the 6607. So, my other recommendation is to stick with a full synthetic media oil filter, changed at every interval, and use the oversized if it fits(simply verify).
