The common solution found in European cities is to have one street reserved entirely for pedestrians, and to allow delivery access from the two adjacent, parallel streets. But of course this requires a certain amount of infrastructure within the buildings.

Yes, and obviously it only makes it possible to make half the streets pedestrian streets in an area. To make every street in an area pedestrian-only you’d need a different solution. Deliveries can often be handled in early mornings for example.
