Hardibacker fibre tape and adhesive will suffice imo.

Would you use a polymer adhesive or non polymer adhesive or would that make little difference
Just want it all prepped good for when I get the tiler in

Nearly all cement based adhesive are polymer modified.. 👍 , the adhesive just adheres the fibre tape to strengthen the joint..

S1 Adhesive will be fine , make sure to silicone the tray to the walls as well when you bed the tray in.
