Well, from my experience I've learned a few things.
I agree with using F-Smash to go for kills, but a combo I often see people using that carries on from other characters is the good old spot dodge + down Smash.
It's not necessarily a bad habit, but if one was to mix in Up Smash to their game when they've just dodged an attack from behind, they'd be improving their game a nice amount. More range, speed, and power in a situation is always nice to have. I've never really gotten kills with Downsmash, but Upsmash has gotten me some surprise kills.
Depending on the lag of the attack, Down smash might be best for foes in front of you because I believe it has more range than upsmash and more speed because it takes time for Luigi's head to get from back to front during the Upsmash, while the Downsmash works the opposite way (front to back).
In that situation, and Downsmash seems to be about the same speed as a uptilted Fsmash (maybe faster, but you're saving that Fsmash for killshots anyway so you'll want to Dsmash if they're at lower percents).
If I'm right, than this means each of Luigi's smashes are very useful depending on the situation, which is an awesome luxury not all characters have.
Of course, Luigi's strength lies in the air, but even on the ground he's still very powerful.
