I admit that I am somewhat biased, but the most beautiful music at a wedding is music played on classical guitar. These are some of the songs I have transcribed for guitar and played at weddings:
Canon in D by Pachelbel
Jesu Joy of Man’s Desiring (from Cantata 147) by Bach
Ode to Joy (from Symphony 9, Opus 125) by Beethoven
Bridal Chorus (“Here Comes the Bride”) by Wagner
Wedding March (from Opus 61) by Mendelssohn
Learn this music and next time you are asked to play at a wedding, you will be ready.
