To me as a user, \once\override is used to change the next note (or
items attached to it) and \single\tweak is used to change the next
item.

That \once\override applies to the next timestep, and the
following note incidentally happens at that timestep is an internal
detail when I'm writing a score.

To me it's basically the same as the \set / \override distinction. It
might be a different concept to anyone who knows the internals,
but to a user both are used to change the default.

Cheers,
Reinhold
