Plants will grow without issue in plain sand, no substrate fertilization is required so long as the water column nutrition is met.
For aesthetics, that is your call. You can swap out to any other substrate (that doesn't leach ammonia) without having to cycle it. Worth looking into.
Aquasoil is a buffering substrate, so your pH will drop and kH
will drop until you exhaust it's buffering ability (assuming you aren't using RO
/ distilled water).
Plants spreading through substrate is easily achievable in plain sand or fine gravel, aquasoil as well. Cleaning the substrate is much easier done with sand or gravel, almost impossible with aquasoil.
What are your goals with this tank?
What equipment are you running? (Lighting, CO2
What fertilizers are you running / plan to run? And how much how often?
How large are your water changes, and how often?
