I feel like an Apple TV plus 2 homepod minis work well enough for 90% of people’s viewing situations, and Apple TV plus 2 homepods for 98% of situations. That would cost $330 to $750 plus tax and less than 5 minutes of setup/research time.

The time and money cost of going further than that is not going to provide a sufficient return on investment except to a very small proportion of people.
