Just remember, you can always change the tag if it wrong or could be better described with a different feature. I would recommend nodes tagged with individual features. For example, a nearby grocery store also has a coffee shop, run separately from the grocery, and a bank branch inside. One option would be to tag the building with the grocery store with two separate nodes, one for the coffee shop and one for the bank. Additional tags could be added for ATMs, restrooms, etc. Another option is to leave the building as building=yes with separate tags for all the attributes. My preference is based on the purpose of the building. If it a multiuse building, leave the building as just a polygon tagged building=yes. If the building was built for a specific amenity, such as grocery store or hospital, then tag it building=yes with other appropriate tags. > > Another question.

I tend to pick the one or the other, depending on what you think is it major feature. But either way is probably correct.
