Yes, for full resolution@60Hz you need the Usb-c/Thunderbolt or Displayport connections. HMDI only manages 30 Hz with 5120x2160 - so the HDMI connections are relatively useless - unless you want to connect a Playstation or something in between and enjoy black bars left and right. Or for Picture-In-Picture or two PCs side by side.
Among the TV wall mounts there are some that should fit the screen. Simply enter a minimum weight of 14kg and VESA 100x100 in the filter and select. You may need to ensure that the dimensions are not larger than the monitor itself.
