Use a work address, email address, and a cell phone number. Agreed that home address is a bad idea, just like on luggage tags.

That would require the finder/thief to be in a position to exploit that knowledge, something that is fairly unlikely for the general case. There are easier ways to figure out if I'm home (ring the door).

If you're concerned about that, just have a dedicated email address on the screen.

I usually put a friend's email/phone on my phone's lock screen. That way they actually can contact someone (since I just lost the means to do so). I hope a potential robber wouldn't take this as info of a good target, though.
