You're correct that the war advanced technologies that already existed.
You mentioned the telegraph. In 1843, Congress appropriated money to lay telegraph wires from Washington to Baltimore. Mr. Morse was off and running.

Coincidentally, in the same year, the USS PRINCETON was launched. It would be the first screw powered steam driven ship in the US Navy.

War, being the ultimate emergency, drives the development of technologies, new and pre-existing. You can argue whether or not its worth the price.
