The A520s are great pedals and were (until recently) my favourite for commuting and touring.
I like to have “proper” SPDs on my faster road bike – the one I use for training, Sportives etc as I’m convinced they are more efficient. However, they are a faff for walking about in.
An MTB-type shoe and cleat is much better for commuting (if you have to stop-start and your track-standing is pants) and also for touring when you want to get off your bike and walk about a bit, visit cake shops etc. The cage on the A520 will give your foot a bit of support and might help prevent a hot-spot on your sole from all the pressure being on the cleat nut.
Last year, I converted to Crank Brothers Candys for commuting and touring.
