So, my question is, are clipless pedals appropriate for an urban commuter who has to stop frequently, or are they better suited to long road trips?
Yes, clipless pedals are appropriate for the urban commuter.
I live in Atlanta (
LOTS of traffic

) and have Shimano M535 (SPD) two-sided mountain bike pedals on my commuter.

They work great in traffic when you might be "hurried" by the cars behind you since they are two-sided. Don't have to worry about them being upside-down like one-sided pedals (Look, Ritchey, etc.).
Clipping in and out is easy.
