The Windsor Tourist that you offer is pretty close to what I want, but these are the changes I would make:

Tires: Kevlar belted tires for puncture resistance. For commuting in the city, flat resistance is a big deal. 28-32 mm wide. Reflective sidewall for extra bonus points.

Shifters: Good quality bar end shifters. Practically no bikes locked up outside my office have $200+ shifter-brake combos. At least not for long.

Brakes: Aero levers with cross-type interrupters. Keep the cantis. Maybe the new Tektro R556's if you really want a sidepull.

Fenders. Ones that stay put. Just ordered a new set of Freddy HC's because my current ones keep working loose at the stays.

Gearing. No triple chainwheel. I don't need to climb or descend the Rockies. Right now I run a single 44T chainring up front. If I ran a double, the most the big ring would be is 48T. I really didn't spend much time in the 53T ring when I had one. [edit] I see from the previous post that gearing is really location dependent. I'm in Chicago, which is about as flat as it gets.
