I'm working, I don't have time to look at everything
Lumens is a measure of the amount of light produced by the bulb overall, the plant will use photons, which are measured in mol (or µMol) at the leaves of the plant. so not exactly the same thing, but for your purposes, go with more lumens, and assume they mostly go onto the plants.
get whichever works best for you, make sure it is the right size, and will cover enough of your aquarium in light. don'tt overthink it, don't worry too much about 6500K,. By the time you have finished overthinking, you would already have a planted aquarium.
