What about the part that says "where they are protected by an
approved raceway"? They are not talking about everything enclosed in a raceway, they are talking about either the LV or the line voltage conductors being enclosed in a raceway, this raceway is then run with the unprotected conductors in whatever they are enclosed with. This creates a barrier between the line and LV.
Unfortunately, this was probably written by AI because previous versions used "non-conductive sheath" instead of "raceway". This made it clearer what the intent is but it seems all logic is lost with the NEC.
Which, for example, would allow 16awg or 18awg TFFN where the circuit is functionally associated with the power circuit, which fron what I know I would judge the OP's 0-10 lighting control to qualify for.
No. "functionally associated with" has forever come up as an excuse to run LV and line conductors together. Nothing new. Fact is that "functionally associated with" means that the fixture (in this instance) cannot operate without the LV conductors... which is false. It will operate just fine, just not dim.
Rarely does "functionally associated with" ever hold true. An example where it would be true is the 24V coil conductors inside of a 277V contactor enclosure, for instance. The contactor could not operate without the control wiring.
