Are there any tickets that may be useful to you? Yes, many.

Is there any one ticket that will be of use to you in all locations? No - with the possible exception of a http://www.britrail.com/ pass for travelling between Oxford/Edinburgh, and going on excursions out of those cities.

With regards to Oxford, the local government provides this page - https://www.oxford.gov.uk/info/20012/parking_and_travel/495/public_transport - it appears there is no unified ticket availble for the many companies involved.

Edinburgh is a bit more unified, with the newly formed Transport for Edinburgh, but again they don't seem to provide unified tickets, and don't have involvement with all the bus companies in the city.

With regards to Oxford, the local government provides this page - https://www.oxford.gov.uk/info/20012/parking_and_travel/495/public_transport - there are several bus companies in the Oxford area with their own ticketing regime, but apparently Oxford Bus to operate a unified bus ticketing system https://city.oxfordbus.co.uk/smartzone/

Edinburgh is a bit more unified, with the newly formed Transport for Edinburgh, but again they don't seem to provide unified tickets evne for their two services (Tram + Lothian Bus), never mind with the other bus companies and rail services operating in Edinburgh.
