Which exercises do experts commonly recommend for toning the thighs?

Cardio Mix: The best way to lose weight is cardio and a balanced diet. However, do not always do the same exercise or you will increase your risks for stress injuries. Mix things up with running, biking, swimming, or circuit training. Ultimately you need to burn more than you consume. Exercises such as crunches, planks, sit-ups, etc are good for toning the abdominal muscles, but cardio is best for weight loss.
