I was thinking more like Titan IIIE Centaur rather than Atlas Centaur seeing the Starship could get ~7 Centaur D-1T's to LEO.
That said you are right about feeding everything metholox for simplicity, if they are still looking at those little landing engines for Starship HLS they might be a solid option and a second use for the same hardware. That would be more than enough for realistic commercial / military GTO missions and if they really want to throw 20 tons at Mars a single Raptor would do the job fine.

Unless the Starship in pic related is falling at ~30 meters per second, the thrusters will be controlling the descent for more than 'a second or so'. Just so everyone knows, 30 m/s is 108 km/h or 67 mph. Not exactly a soft touchdown.

In reality, this Starship would be landing at ~1m/s. If you are right and these thrusters cannot produce a TWR equal to 1, and the Raptors shut down when the Starship was moving at zero velocity, that means that the thrusters would need to be able to pull at MINIMUM a TWR of 0.96, in order to only accelerate by 1 m/s over the course of a 30 meter fall.
