Personally a one engine plane for 'business' is a non starter...after that it's coming down to capital and operating costs...then somewhere in here we shoe horn a plane into the boss's 'mission' which will morph once they start flying around.
Short field performance is really more about pilot limitation then aircraft limitation...with few guys actually having the skills to safety get in an out of tight fields.
As far as 'modern' goes, the Piaggio with a Canard, rear engines..is as modern as it gets.
