could it be that your spoke calculations were a little off and the DS spokes are too short? I put your specs in a spoke calc. and the lenghts it provided were: NDS 279mm and DS 275mm... and 3 mm are a massive difference in spoke lenght

How imbalanced should they be for a modern rear wheel?
The tension ratio for a wheel with the same number of spokes each side is the ratio between the flange offsets from the spoke holes, i.e. after allowing for offset or stagger. On a non-offset rim to a road rear, that can easily be 2:1, which would give a frequency difference of half an octave since frequency is a function of the square root of tension.

Very imbalanced, hence 2:1 triplet lacing patterns. It's not unusual for the NDS spokes to be only 60% of the tension of the DS spokes with the same lacing patterns on both sides and the same spokes. You don't really have all that many options - the wheel needs to be dished properly, and once that's done the spoke tensions are what they are.

I'm struggling with excessively imbalanced spoke tension. How imbalanced should they be for a modern rear wheel?
Rim: 24h Light Bicycle R35 (35mm carbon rim)
Hub: Bitex RAR9 rear w/ 11sp freehub
Spokes: Sapim D-Light - DS: 272mm, NDS: 278mm
Two cross
DS spoke tension: Quite high indeed, only slight movement with squeezed, average note of C above middle C when plucked
NDS spoke tension: Quite low, does move a lot when squeezed, average note of middle C
Dishing is still off, needs to go still 4mm+ towards DS.
I do feel slightly silly quoting musical spoke pitches on this thread... time to buy a spoke tension meter?
