One angle missing from your list, as the person who dictates rather than types: some of these are not about supervision at all, they are about input.
The voice ones are solving "I cannot type comfortably for an hour", which is a different problem from "my agent is blocked". They just look adjacent because they wrap the same tool.
If you have no input problem, that entire branch of the category is not for you, and evaluating it against your multiplexer will make it look pointless. It is not pointless. It is aimed at somebody else.
