Why are you considering turning CEC off? Leaving it on should enable you to control your AVR volume with your TV remote and Minix remote as well as automatically switch to/from the Minix input. Plus you pretty much have to leave CEC on in order to use ARC to get audio from your smart TV to your AVR.
Obviously a single universal will control all your devices and automate the task of powering up/down everything at once and switching inputs (something CEC is probably doing now). CEC interferes with the commands that Harmony is sending, so it has to be turned off. You also have to find an alternate solution to ARC which usually involves running an optical cable and managing another input.
I'm a huge universal remote proponent. But, I find that my TV remote and CEC does 99.9% of what I need to do these days. On the rare occasion I watch a disc, I grab my universal. Otherwise, I just use the TV remote for everything.
I do question what purpose the Minix serves if you have a Sony smart TV which can presumably do just about everything the Minix does, especially if you put your audio/video library on a sever and access via Plex or similar.
