Absolutely the simplest, safest, most reliable, lowest cost system

Safest? Not if you you use it the way you do!

Plug one end into shore power, bring the other end on board ...

The golden rule of shore power is that you attach and secure the boat
end first and then the reverse when you disconnect.

Walking around the dock holding a live plug in your hand is dumb,
dumb, dumb. If you trip and go into the water, you're just going to
flounder around conscious and wondering why your hand won't reach for
the dock edge, and your feet won't kick. Bad way to die.
