Reddit reviews Ultimate Christmas Fakebook - 6Th Edition

I've used this book for most of my Christmas stuff for years and just take requests. It's just a fake book full of lead sheets rather than fully arranged accordion fare, but you can make a pretty good arrangement of almost anything just playing fairly standard left hand patterns and playing the written melody in your right hand.

If your theory knowledge stretches a bit further, you can make a more interesting right hand by adding harmony or moving lines beneath the melody.

I have this.

If you know chords it's the best option out there I think.
