I would ask around in places that actually have sun (the southern US or the tropics).
Sewn-on Sunbrella covers last until the stitching fails (5-8 years) and can then be resewn by hand for another 5-8 years. More if you don't sail often. The Sunbrella will last the life of the sail, and darker colors block more UV. White sailcloth UV covers are a bad joke--they don't last and they don't actually block UV and they don't last. No glue, that just makes replacement and restitching more difficult.
Do not stitch cover to laminate sails. They'll tear. Try self-adhesive, and don't expect the sail to last well on a furler.
