Have booked a violin and cello for the ceremony. Looking for recommendations for either a modern love song or a beautiful classical piece

Hi ladies! We are getting married in Sorrento, Italy and have booked a violin and cello for the ceremony. I’m driving myself mad listening to music for walking down the aisle and during the service. I wanted a modern song but some sound completely different on strings. Looking for recommendations for either a modern love song or a beautiful classical piece. Thanks so much xx
