Anthony,
I had a long talk with Micheal Harding, the paint maker. He is particularly persnickety about procedures, mediums and paint quality.
He said quite emphatically NOT to paint oil over acrylics, including acrylic sized canvas.
Oil primed canvasses are the best, and if you can get one properly made and cured, lead primed canvas.
He also suggested that the MOST archival surface in his opinion was MDF board, cradeled and simply sized with two coats of rabbit skin glue.
The best medium is simply the best refined turpentine you can find.
He was aghast that I would buy an oil primed canvas and tone it with a Liquin or Gaklyd wash.
