Well the numbers you quote for the Argon are not anything like the number suggested by your fit. The Argon geometry is essentially a road bike geometry. The main thing making it more CX is being made for wider tires than many road bikes and the components and gearing more suited to CX.
If you want to get a bike, go shopping for a bike. Sitting on your computer might get you a bike, but you won't know for certain it fits you until you get it. And I have seen some bikes on the manufacturers website that I thought were aesthetically pleasing and the bike I had to have, but when I saw them in person they were just ugly.
Something isn't right with your retul fit. I thought the retul fit was also supposed to suggest bike models that matched what they come up with based on your measurements. Did this one not suggest anything? Of course as wacky as those numbers seem I guess it couldn't find anything.
