There really is no right answer, just what works best for you!
I haven’t seen the Chorus Stellarum in person yet, but have been devouring images online since the early previews, as this is my favourite release of the new season. I have a couple of CLF double face, which have similarities. What shows will depend on how you tie it; do you have any preferred ways to wear?
For the first one, you could hide the light border with a bias fold and simple necklace knot. Or by folding in half, or thirds, and tying the matching corners behind the neck (I like this way to show the mid sections of a scarf and use it a lot with CLF). This one has the darkest background palette of the ones you have picked, but the way it is tied here actually makes it look like the lightest option.
Folding on the opposite bias of the green will pretty much hide the red and orange accents, but you would also lose the horses and riders, which are a key feature of the design for me. If you’re happiest with the colours overall in option three, this will probably give you the most typing options. They're usually darker in real life than the flat web pictures, so I expect all three would work well with dark clothing. The green especially would pop.
Good luck choosing and be sure to post mod shots when you can!
Edited to add that the horizontal folded tie described above may be a little fiddly with a 70!
