For HOB, Tidal is best in class (IMO). It's self priming, has a sicce pump, and skims. I wouldn't worry about a canister or media types, as you're not going to max out any filtration with a 9g tank. A simple sponge cut to fit will be fine.
As for lighting, it doesn't really matter without Co2. Don't believe that adding more par is going to result in more growth. Just look for something with a plant spectrum. Kelvin, lumens, and wattage mean absolutely nothing. I would put the $30est 12" light on the tank, and that should get you close.
