I'd seriously consider unifi gear, like the other comments seem to have also suggested.
The only thing you don't get is ethernet drops out of the APs or anything like that, but the UAPs in a mesh configuraiton could proabbly do everything you want, unless you have a shockingly large piece of property.
I'm sure an AI babysitter won't be immediately and utterly broken and bypassed by every single kid in these "classes".
(Seriously: we're talking about 8-12 year olds here and the absolutely are smart enough and incentivized to break the ever-loving crap out of this stupid idea.)
