Cleaning for me is pretty much rinsing out all hot side equipment very well (with deep cleaning by long PBW soak, scrubbing with scratch less pads, and full breakdown of valves and weld less bulkheads 2-3 times per year), then good cleaning with PBW, good rinse and sanitizer for all cold side equipment (hoses, pumps, fermenters, air locks, kegs) right after every use and rinse and sanitize before next use. I store my kegs charged with CO2 and a goodly amount of Star San foam residue to further inhibit nasties growing - then I blast it out through the dip tube before racking the next beer onto/under a bed of CO2.
It sounds like some of these processes used are overkill, but it's your time and your peace of mind....so go with what suits you!
