to hide the user input to be displayed on screen, use the terminal line setting command stty -echo, whatever the user enters after this command will not be displayed in the screen. to make the input characters get displayed on the screen use stty echo

Is this a statement or a set of questions? What are you trying to accomplish or what are you trying to explain?

I think it would be easier to hide standard output by just redirecting (to another file or /dev/null or whatever...).

If I were that worried about what the system would show based on CLI output, I'd either dump the results to file or /dev/null or wait until no one else is around to observe. Most of the time, I rely heavily on stdout...kinda defeats the purpose of nullifying it.
