A much simpler option here (as many cafes near me have done) is simply put a sign up saying "no laptops". If someone is using one you tell them to leave.

I assume there's a balance. Never run a coffee shop but it seems that a lot of the sales are takeout, so exactly what does and doesn't go on in your seating might well be a secondary concern. If you prioritise folks staying for 5-10 minutes you might just end up with a lot of empty tables.
