The most enjoyable cities/suburbs I've experienced around the world have been fairly dense in terms of narrow streets and multi storey buildings. 3-6 storey buildings on average. NYC and SF already have a good amount like this, though still dominated by roads. There'd also be scope to turn parking lots into actual parks or multi-purpose areas for events, food stalls and so on. Parking lots are just grim.
