I recommend making sure the TV you get will auto recognize an input and turn on / switch to the right input when you turn the device on or plug it in. The LG I have does this with the last generation Apple TV (with the Siri Remote) and with the Nintendo Switch. I would say if you use the switch, this is an almost mandatory feature.
My LG can do this, but I've actually disabled it. I use a universal remote that automatically turns on the TV, receiver, and whatever other device I intend to use and sets everything to the right inputs, and if I let the TV also try to auto-switch inputs then the TV and the remote end up fighting each other. 😄
