I think you are confusing with the descend. Our SOPM and FCOM clearly state that Standard will be set at earliest « at transition altitude »and for the descend, QNH will be set when « clear to an altitude & approaching the TL ».
Besides, you don’t know if you will be asked to stop climb for any reasons.
Saying that I’m personally not to fussy about it. In my homebase, the TA is 9000 feet, and we are sometimes clear to FL110. If we don’t set standard early enough on a very light A319 we do sometimes get alt* before the TA.

Like you, I often hear « Climb to 3900M on standard » or « Climb to flight level 3900M ». The word « to » is often intentionally ommited to avoid confusion when they use « on standard ».
I have no reference but I guess it’s just easier and less confusing to say « On standard » when it’s preceded by Meters.
