I use a 32" Samsung TV -- neutered without wifi -- as my secondary monitor when I work from home. A single HDMI cable transfers sound and graphics to the TV. If you want to add a cable to a dock that provides all the other things you mention, you can do it with a single cable from a laptop to the dock. A phone may require a special converter, such as a Lightning-to-HDMI cable with passthrough power. Or you can use wireless charging if your phone is capable and simplify things a little bit.
The whole reason you want to use a separate dock is that interfaces and connections change very frequently. It's easier to get a dock with everything you want in it than try to get a decent TV also with every connector you want in it. For instance, this TV is going to need a wire with a plate for wireless phone charging, right? How long of a wire at what gauge? No, seriously, different wattage wireless phone charging solutions require limits on wire length. Same for the larger phone / tablet chargers, it often makes a lot of sense to use an electrical extension cord to get the wireless charger close to where you need it rather than extend the charger cable.
In the computer industry, different adapters have come and gone over the years, it's the same thing, better to have a dock you can replace than have a TV with the equivalent of yesterday's SCSi / serial / parallel interfaces on it.
