According to the charts HTD 5M is well in the charts for what you will use it for. I would say 25mm wide and steel corded. I wouldn't go with other braids cause Kevlar and so stretches. Pulleys should be 20 - 22 teeth. Make the ball screws placement and design so that they are only long for the exact necessary travel. Dont overextend them cause its easier to mount or for other reason. Pulleys should have fitted bronze bushing and the bolts/shafts should be proper ones. Shoulder bolts if you use bolts and steel shafts, don't leave them to rotate without bearing in between.
PS, some additional info:
