On android, CDisplayEX can be used to sync read progress and it has direct API access to kavita. It doesn’t use OPDS. You’ll have to get the pro version of it to hook up to external sources though.

You can host your own kavita email service to send books to kindles. Amazon devices don’t have 2 way communication so they can’t report read progress back to the server.
