On the airbus it's easiest to just think of the thrust levers as thrust limiters (with A/T engaged of course). Typically the thrust levers will be in the CLB detent from thrust reduction altitude until the flare. Obviously the thrust will vary throughout the flight but the levers will be stationary.
In manual thrust they work the same as any other aircraft.
I think some of the smaller Embraer aircraft do not have auto thrust installed but don't take that as gospel!
