What processional songs sound good on an organ?

The church we’re getting married at has a beautiful pipe organ and an organist available for us to use/hire but I’m having a hard time
finding songs that aren’t overused or too stuffy sounding that sound good on an organ. They do have a piano/pianist but this organ is really cool and I would love to use it.

I do like pachebel’s canon in D but is that overused? What songs are you ladies using if you’re using an organ?

Thanks!
