Are you looking for a mesh wifi setup or can you run an Ethernet cable to each location you want an access point? If you can’t run a cable to each spot then an off the shelf mesh wifi system is still your best bet, there may be some that are less cloud connected but they are meant to be dead simple so that usually means an app and a cloud service of some sort.
If your just looking for an alternative to content and ad filtering for the kids I would recommend AdGuard for a partner friendly setup and Pihole for a more enthusiast setup.
