Is there a way to guarantee a mobile device or tablet can only access my own services and block all other traffic? (lemmy.world)

a private DNS server that only has records from your local services would at least prevent apps from reaching out as long as they aren’t smart enough to fall back to an IP address if DNS fails.

Yes, this. It's important that your local DNS server does not even forward queries from the isolated subnet to external DNS, because these queries (and responses) can contain information. ("DNS tunneling").
