It does depend on the country - for instance in the UK there is a traditional preference for a lever lock as the main door lock, with a "Yale" (cylinder lock) only for short-term use. That's become less common with modern doors with Eurolocks, but most of our housing stock is old.

As to professionals: from my limited experience when they are dealing with a cylinder lock they will start with a stiff plastic card to push the bolt free, and if that doesn't work, the next thing is a hook tool through the letter box. Attacking the cylinder itself is well down the list.
