Oooh yes please to that cider combination! I think a good ripe Eleagnus fruit has a bit of a strawberry taste that would go amazing with peach.
Glad you found a good one; I remember I had found a really good m, flavorful, sweet one as a kid that got cut down π I was a bit sad, though it was growing right next to the magnolia my parents were trying to grow, so I understood.
