Is this a one-off offering or is this a business model?
If it is a one-off, run an 11-28 with a 52/36 or 50/34 and a GS RD and call it a day. It is really about the chainrings and the RD (max/capacity) than the cassette. People swap out cassettes and need a RD that will accommodate the swap. The wider the non-specific buyer pool, the more flexibility you need to offer.
If it is a business model, you need to define your market for your product first. If you can’t identify who will buy your bikes, no one, especially on an internet forum, can tell you how to set them up.
Also the more local the sale, the more local knowledge is needed.

Edit added: 10 speed cassettes are old technology. That in itself will cut your market drastically.
