Buy the right product, not the one with a few bells and whistles that sound cool.
RF is highly proprietary and HDMI CEC is non-standardized so it often is flaky to troublesome when in use.
Instead, as mentioned, you should be looking for a good RF remote control system that is well reviewed.
The Harmony remotes from Logitech are by far one of the most popular for the home user as you can program them yourself, and use both IR and RF commands to run your gear. RF is extremely proprietary, so you don't really control your gear via RF, but you send commands to a RF receiver, that then converts the command to infrared (IR) and you put a IR transmitter on the front of devices which need to be controlled.
AV receivers, TVs, projectors, cable boxes, BD players, etc. are all IR controllable, and the RF receiver can handle running the show nicely.
Having controllable equipment is the key to make it all work best. Yamaha, Pioneer, and Denon all have very controllable gear via IR commands and will serve you nicely. Sony and Panasonic components (TVs, etc) also have good IR commands. Samsung BD players do NOT! But their TVs do. As do Sharp TVs.
Lots of options out there, but you really should be looking for a good product first and foremost, then put the controls in on top of the sources.
