Interesting choice of bikes. Hopefully it will treat you well. It seems to have a lot of good compromises.

5 miles is a moderate commute. Not long, not short.

I am a big fan of toeclips (or clipless pedals, but for a daily commuter, I'd go with plastic toeclips & street shoes).

I was going to suggest also keeping an eye out for good used bikes. Or, perhaps a good used "road bike" will be your +1 bike sometime in the future.
