There's no "correct" solution, headmaster. You use whatever the
situation requires.

There are several correct solutions and lots of incorrect ones, using
toggles is not in the correct solution camp, none that rely on the
plaster board for strength are.
Plaster board is not a structural material for anything much heavier
than a clock.

"A small 1/8" toggle can safely hold 50 lbs on 1/2" plasterboard... a
3/8" toggle over 100 lbs"

A tv arm may well merit stud fixing because of the in/out stress on the
fixing. Sheer strength would be ok I'm sure
