But what about a jet engine? Here the thrust comes partly from flinging
back air encountered on the way and partly (admittedly a small part) from
ejecting burnt fuel which is carried along like a rocket's propellant. Is
there an inbuilt speed limit in this case? My intuition says there is not,
but I'm not convinced of this.

The speed limit that comes to mind is the need for subsonic inlet
air for efficient compressor operation. That makes supersonic
flight a question of slowing the inlet air then speeding up the
air exiting the engine.
