Choice will depend on what you use your bike for - commuting, leisure rides at the weekend, racing etc. For what it's worth, I use SPD pedals/shoes for commuting to the station in the morning and the odd weekend spin, as the shoes have a recessed cleat to help walking in the shoes. Even with SPD shoes, for example, there are variants - mine have a stiff sole which is comfortable for spreading the load over longer cycles but not so good for walking any distance (I only walk through the station with a short tube journey at the other end).
I'd add that it may be worth getting used to your new bike before launching into clipless pedals/shoes. I found the transition difficult when I first got my bike. However, after leaving it 3 months or so, the transition was much easier once I had gained confidence on handling my new bike (too much to think about previously when trying to get used to 2 new things).
