cozmo. I have a rock64 2gb board and a 55" 4K TCL TV.
I use CEC with my TV on the latest test release. I did notice that it didn't take effect until after I rebooted. Also it does not work within a few seconds of the system going to sleep. However if I waited a little bit, the TV would turn on.
I have not noticed any USB keyboard issues.
I have not seen issues with hanging videos when skipping.
My 4K HDR videos seem to play fine. I had to force the TV to HDMI 2.0 for the HDR to work however.
I also see the green flickering horizontal lines previously reported in the GUI when it is running at 4K res.
You might try this fix someone reported with similar issues.
Physical keyboard unresponsive after upgrade
Does anyone know how to remap the browser backward buttons on a Logitech mouse?
I used to be able to use them to go to the previous menu. Now they do not function at all.
I had seen a fix about this on a older kodi 15->16 upgrade, but for the life of me I can't find that post anymore.
The gui keymap utility does not work for me on these mouse buttons.
For reference, these thumb buttons.

I finally pieced together enough of the mouse keymap to get a working back button.
Here it is if anyone else wants to try.
You might need to try numbers 5-9 for the click id depending on your mouse, and some people might prefer
This would have been so much easier if the Kodi mouse keymap Wiki had something other than "Further action required"
<keymap>
<global>
<mouse>
<click id="6">Back</click>
</mouse>
</global>
</keymap>
