So I did a bit more research into Gravity Forms and found they include a feature called “conditional logic” which might do exactly what I need.
I also need to install the Gravity Forms Product Add-ons to be able to apply the conditional logic forms to products.
Links to these plugins/add-ons are below for anyone trying to achieve something similar.
