I'd like to believe that football is a team sport and any goal that involves the whole team is a "beautiful goal". It is a reason I like Arsenal play because they share the ball a lot and move it about really quickly from defence to attack. I don't have any specific examples to cite. As far as individual goals go, I don't believe many players have dribbled past 7 defenders including the goalkeeper to score ala Maradona. John Barnes also scored against Brazil for England after a superb individual effort.
