Thanks for this circuit, I will try to modify it to consolidate parts and make it suitable for 16v input.

The rest of my questions needs more investigation to be solved.

That circuit will work fine at Vbattery=16V. If you are concerned about exceeding VGSmax (+/-20V) stick a 10V zener across the gate and source.

I intend to have a 13v zener diode elsewhere (input of DC-DC module), so I will put another one for this circuit. Also, probably getting consolidated parts like 10k or 100k resistors only. putting a small cap on the on-off switch will help in bouncing effect if it happens with a traditional switch (not tactile button).

You don't need to debounce the switch - the capacitor across the gate-source will do that for you.

Nothing new here but re-arranged GND stuff to be referenced in a better way, still the circuit is the same.

Now GND is the battery negative and I assigned "float GND" to the floating supply circuit.
