That’s a bitch of a wall to put a control or expansion joint in. You have to do the best you can to confine its size/length (along the wall)/shape to a fairly straight line. I would use some sort of closed cell, soft foam, sheet material about .5” (+/-) thick in most of the joint width (wall thickness), to keep mortar out of the joint. I would stop this short of the wall outer surfaces, with enough joint depth for a proper sized backer rod, and then caulk the outside of the joint with a properly proportioned bead of caulking. Talk this over with a good mason, so you and he know what you want and what you are getting. Lots of them will butcher this if you let them. Talk with a good masonry supply house for ideas and specific material names.
