Yes, you definitely can.
Regarding the “smart” features, they all have Netflix, Amazon Prime, Hulu, YouTube, etc., but I would recommend either a Roku TV or an Android TV. The reason is that these TVs will continue to receive support and updates longer than smart TVs from companies that are using a custom smart TV interface.
Get a mount that at a minimum allows tilt and swivel. The tilt allows you to direct the TV downward a few degrees if it’s mounted higher on the wall. The swivel allows you to correct a few degrees for a mount that isn’t perfectly level. Be careful with articulating mounts that can be pulled out from the wall (sometimes up to 2ft) and then angled left or right. The ability to move the TV that far means any cables plugged into the TV need to be able to move the same distance and it can be easy to pull on them and break things.
Regarding clutter, you can eliminate almost all wires by getting a smart TV that connects to the internet via your WiFi. I say almost because the TV still needs a power cable. It’s against electrical code to directly run your TV’s power cord inside the wall, so your choices are either to hide the power cord in a surface mounted conduit that is painted the same color as the wall, or, ideally, you will add a power outlet directly behind your television as part of the wall-mount installation process, but that can be costly if a power source isn’t convenient in the location you want to put your TV.
