Most people’s gut reaction is probably to hire someone under intern like conditions.
Ie a young candidate whose main motivation is getting something on their resume and therefore will suck up to you and go the extra mile. OP recommends the opposite: someone who doesn’t go the extra mile, but will be stable and reliable for a very long time.
Think about it. People going the extra mile do it because they want to go beyond what they do. They risk burn-out - in which case they can't do their job anymore - or they move on - in which case you lose an employee and have to find another one.
"Intern-like conditions" has an undertone of exploitation to it; nobody should be exploited.
