(btw, it can be further reduced e.g. by removing two.ly)

No, a problem is that \cadenzaOff doesn't mark the end of the bar (there will 
be four beats before the candenza bar is finished).

I guess it'd be something like
\set Timing.measurePosition = #(make-moment 1 4)
where you now inserted \cadenzaOn. But I don't know, so please experiment.

That's becaue you don't end the cadenza within the repeat. Repeat unfolding 
works in principle by copy&paste, so you will have two \cadenzaOn:s followed by 
two cadenzaOff:s in your example; this may give unexpected results.
