disagree, medium for single chainring if you have a wide ratio 11-36 cassette
Short cage is supposedly good for 27T difference, but I reckon that’s a bit tight particularly if you might eventually go for an aftermarket bigger rear cog like a 40 or 42 that are starting to come available. And given the benefit of a short cage is better tension / reduced chain clatter which is what the clutch does anyway, i don’t really see the benefit.
The Zee is specifically designed for 11-36. None of the Shimano Mechs are designed to handle those 40/42t cogs, they’ll all struggle to get far enough forward, so it’ll be a bodge either way.
