How else would we teleport matter, if it wasn't via information representing that matter?
Critical point: for each particle you want to "teleport", you have recipient particle standing by to receive it.
I'm not certain whether somehow mass-entangling an entire object with something else that receives its state and becomes a perfect (or near perfect because real life doesn't have "Heisenberg compensators" like Trek, to compensate for the Heisenberging) copy of the original is more or less ridiculous than Star Trek's version.
Not everyone thinks in terms of Star Trek...
Is it ever explicitly called out that teleportation instantaneously moves matter?
I'm not a huge fan, but from what I've seen there is a max range they can teleport. Even taking them orbiting a planet, it usually take about 2-3 seconds or so for the teleportation to go through. Transferring state via EM waves at the speed of light (300km/s) that still gets you between half a million and a million kilometers distance in 2-3 seconds. Seems like plenty range to not need anything instantaneous.
No. Maybe "relatively instantaneously" would be more accurate. Although if we're considering the concept of teleportation as a science fictional plot device in general, it depends, and even within Star Trek, the transporters worked however the plot required.
Trek style transporters did still "move" some kind of matter stream, though. In one episode, the stream bounced off some clouds when an away team was beaming off of a planet and accidentally created a duplicate of Riker.

Notwithstanding the other problems involved[0], sending only state still requires that state to be transferred into some existing matter at the other end.
