Can the sleeves be let out, Simon? The buttoned cuff makes me wonder ...

If it's merely an inch or so you might get away with having an alterationist replace the cuff with a slightly wider one (you'd need spare material for that, of course).

Nah, it would be more like three inches ...

it is a good deal snugger and shorter than the wool 33 Jacket, so sizing up might be worth a try...

Seeing the latest pics at the shop I gotta ask, what's with the cuffs? They're facing outward which is the correct rotation but they're positioned with the button towards the torso instead of towards the rear (the standard position on both tailored jackets and leather halfbelts etc.).

@SJC since you mentioned your new garment tech connection:

The button cuffs on the cotton 33 jacket seem to be in need of fixing. The orientation of button cuffs is always the same, check against originals. They don't point towards the inside (the torso) when the arms are hanging loose but outward at a specific angle. A cuff that points inward simply feels and looks wrong when worn.

This also applies to some of the previous iterations of SJC tailored jackets (not the 2019 ones, as far as I've seen).
The button cuffs of casual jackets basically have the same orientation as the cuffs of tailored jackets. When you cross your arms wearing a tailored jacket, the buttons (and, in case of a true cuff with that fabric fold) always end up at the lower edge of the visible cuff in front of you - they don't get buried by your arms. So it's not just convention, it's a convenience.

Random examples to help you visualise what I'm referring to: where cuffs end up when in motion.







And position one, this:
