I'm not sure that it's an only option, so I'm not going to recommend what I use to you.

I'm not very well informed in the state of the market. I'm sure something should be there which is exactly for you and won't require you reading tutorials or documentation to set up separate isolated WiFi network.

Although I thought earlier that Ubiquiti is exactly that: simplified and well integrated "magic" solution. Maybe a bit overpriced, but still doing their job well.
