Sure, the roof overhang adds something on the first floor. We have a 3 story old building with a mezzanine floor (3.5 stories) and a roof overhang of about 30-40 cm above the entrance (over 10 m high). If it's raining normally, you can press up against the wall and take shelter there to pick up the key. I would do 50 cm all the way around, it's just really good facade protection.
Most homes with mold on the facade with ETICS trim have no roof overhangs.
Especially since it makes little difference in the long run in terms of cost, so it's pretty clear: 50 cm across should be the rule.
