For video chat, you don't need the latest. After the camera on my MacBook stopped working, I started using a 5th gen iPad mini. I use it with a stand on the kitchen table, in landscape mode, and it's fine.

Bigger isn't necessarily better. My wife has a full-size iPad and I find it awkwardly big for most purposes.

But for ease of use for the technically challenged, I think something like a Nest Hub Max might be better, since it will automatically point the camera. Caveats: it's not easy to set up for someone without a cell phone (it's technically unsupported), but once you do it for them, it's easy to make a call. Also, weirdly, the video only works when they call me; if I call them it's audio only. (I ask them to call me back.)
