My parents are starting to struggle so I am looking for a senior citizens friendly remote

Requirements:

--simple

--big buttons (highly desirable)

--have the . or - button to enter channels 7.1, etc. They watch over the air with built-in tuner in their TV

--input button to switch source inputs from TV to HDMI1 (roku box)

--control sound bar audio

--power off sound bar (desirable)

any extras like back lit buttons, all nice to have

Meanwhile, I am reading over the previous thread (remote for the elderly) to see if any suggestions below can apply for my folks as well.
