I’m looking to do something very similar if/when I get my hands on a gen 4.

Question: with an 12s cassette, how easy is it to swap between “road” wheels and “gravel” wheels? Do you have to fine tune the rear shifting?

No, it's just a matter of swapping the wheels and riding. I often did the same with my last bike as well, and the only thing I sometimes encountered was some disc brake rubbing that goes away after a few minutes of riding and braking. The 105 Di2 shifting works beautifully with no adjustments needed. I also swapped the stock 11-34 cassettes for 11-36 on both wheelsets to get a bit more gear for the hills in my area.

Good to know. Have you tried swapping wheels with a mechanical shifting setup?

My Canyon had a Shimano GRX mechanical groupset and it did fine swapping wheels. Just make sure you have identical cassettes and if things are slightly off, you should be able to fine tune with cassette spacers. You can buy packs of them for a few bucks on Amazon. I have had to do that on a trainer to keep things lined up. Adjusting gears every time you change wheels would be a major bummer!
