For harps smaller than 20 strings, I can recommend Kristine Warmhold’s music. You can find it on her site https://www.musikunterricht-lohmar.de/noten-f%C3%BCr-kleine-harfe-sheet-music-for-small-harp/
or at Derwent harps: https://derwent-harps.myshopify.com/collections/all
I have a 15 string lap harp and bought one of her sheet music books aimed at that exact model.
