Based on your response, I would still choose the Surly out of the three bikes you listed.
Yes, C-X bikes do run wider tires than a traditional road bike... but wider tires don't make one bike more 'impact resistant' than another;
one can tweak a C-X wheel just as easily as a road or MTB wheel in an urban setting. Like I said; it's a matter of how you ride, tire
pressure, etc.
The Civilian is a 1 x 9; to make it even halfway capable as a '15% touring' bike you'll need a F DR, crankset, BB and LH shifter, for starters.
The All City has Track/ SS style dropouts; same adds as the Civilian, and also a R DR and a DR hanger (if they even make one).
The Surly gives you the best combination of equipment and frame features to have a true 'all around' bike... commuter, light touring rig,
and a C-X bike for those times you want to get muddy.
Now of course, if the real reason is... you want a SS style frame and/ or disc brakes, then that's a different story altogether.
