No one is talking about specific parts of the equation here.
Lighter wheels will get you LESS traction off the line, due to wheel spin.
AND this is also dependant on tire choice as well.
Lighter wheels will give you better handling and GRIP, as the suspension works better.
This whole 'traction' thing should be more precise in the defenition.
Do you mean " traction: grip off the line"
or do you mean " traction: grip through corners, etc "
Too light will be a disadvantage and too heavy will be a disadvantage.
Suspensions are designed with the specific wheel/tire weight as part of the equation for a best over all ending.
Personally, I always go lighter than stock, but never too light.
And, I always modify my suspension to work better than stock as well.
