There is never going to be a single product that has a great display, a great casting solution, a great app solution, a great privacy solution, a great input solution, a great docking solution, a great selection of leading edge technology, a great content mixing solution, and whatever else you could want at a great price. Apart from such a thing inherently needing to cost an arm and a leg it needs to outdo every best of breed, it's just not possible.
On the other hand what is possible is buying a great display (link a 120 Hz HDR OLED), buying a great dock (thunderbolt 4 doing power, ethernet, and more), buying a great app/casting solution (like a Shield TV providing Android apps and Chromecast casting), buying a great multiview HDMI matrix, and so on and connecting them to the TV with the advent of HDMI CRC making it so you never have to manually adjust sources (excluding the multiview case where you want to see PiP versions of multiple sources at once in which case there is no adjusting outside adjusting what is PiP'd). This all comes with the upside when you want a better display or a new technology comes along you don't have to replace all $$$$ of it at once.
