Cost is one factor, Soil works well, but has a mess factor.
Flourite really does not have much the plants can use in it.
ADA aqua soil etc, are sort of a mid range between soil and gravel, semi cooked clay. Cost 40$ for 9 liters, you'd need -3 bags for the 72.
It'll break down over time, but for maybe 2-3 years, you should be okay if you do not move stuff around a lot and uproot and mask the soil. So it'll last longer if you do not root around in it.
Nice because the entire sediment is homogeneous.
I think given you have Flourite already, might as well just use what you have.
Light is plenty. CO2 or not, that's an age old question. CO2=> more growth, no competition between plant species for CO2, so you can keep a wider range and foreground plants and taller stems together without much issue.
Ferts, well, adding ferts will help some also if you have CO2 or not.
You might dose 1/10th for a non CO2 approach.
