We have done the same search and not found a
PFD with harness. Ended up getting a harness for underway or on
deck at night. and a
PFD for other times.
There has been a similar discussion here:

There seem to be plenty of good harnesses on the market. Make sure it has a crotch strap,
kids slip straight out otherwise.
The littlest admiral has this one:
Baltic - Junior Safety Harness - 0125 forget where I actually bought it. He is 25kg and grew to 10 ft tall the first time he strapped on and went to the bow by himself underway. Has no complaints about wearing it but gives me grief if I'm not tethered on as well.
