Well, it is true that lightweights are faster in Mario Kart, but they can also be slammed around by heavier racers much more easily. This is why I always pick a heavy character if my siblings pick a lighter one in Mario Kart so that my handling is better and I can just slam them off the track if they get too close. If they pick a mid-weight racer, I pick a mid-weight racer so that we are balanced.

In Smash Bros., lightweight characters are typically, faster, that is true. However, Jigglypuff has terrible speed on the ground, being one of the slowest characters in the game. Jigglypuff does have outstanding aerial mobility and speed though. Lighter characters can be killed earlier than most other characters, but if you play them right you can easily outlast the opponent. I guess what I am trying to say here is that you are correct in a lot of the points you brought up, but you must remember that each character is unique and different in their own way, and that it is how a player uses that character that puts one or the other on top.
