No experience but Iād lean towards the one that comes with Shimano 105 mainly for the 11 speed.
That said the cheapest among the 3 that comes with Shimano Sora is not too bad.
11 speed gives you wider range should you struggle to find lighter gears up certain climbs but for new riders, the willingness to shift is also part of the learning curve so the 11 speed might not be useful for you at the early stage.
However it is a lot more flexible if you have it and if you can afford it, go for the 11 speed.
Your thoughts are pretty much right on the money. I was just about to go for the RC520 when they are back in stock later this month.
What caught my attention on this Ultra 500 AFGF is the UCI frame (honestly though...not much use/benefit for me

), 12mm thru axles, and "Made in Flanders", and is lighter.
Yes, 105 vs Sora is definitely a point worth thinking about. Price wise, the RC520 and Ultra 500 are the same.
I already have a TCR Adv. The thought to pick this up came about when I wanted another bike; which is more relaxed and I can thrash around everyday. My first thought was RC500 with Sora. Since that is sold out...my eyes are now on RC520 OR the Ultra 500.
My long term goal is to see if I go broke by this hobby first or my wife murders me first
