At the gate, all standby lists are cleared front to back with no regard to preference or E+, IME. So First will fill up straight front to back, left to right.

And coach will fill the same way. Even if you're on a wide open flight, they will fill up E+ first for no extra charge since the system can't start behind Row 21 for some reason.

You are wrong on the last part - they absolutely do clear standbys into E- now by default as part of the automated process. See for yourself next time you're standing at a gate with some time to spare. This might have been true at some time in the past but it's not true now. You can either look at the cleared standbys screen, or the seatmap itself.
