You may want to reconsider CEC - simply because if it works, it works, if it doesn't well, you'll tear your hair out trying to get it to work. Unless you have a need for it, a quality universal remote like a harmony would probably work far better.
And that doesn't even include the chance you hook it all up and it doesn't work. And doesn't work includes working unexpectedly, like it works, but mysteriously changes inputs randomly. Or doing really strange things like you change inputs and it suddenly reverts.
It's not a feature where I would choose one receiver over another. Rather have a receiver with poor CEC but better everything else, than a receiver with working CEC but compromise elsewhere
