I think I found one who will even go faster. he has a little higher inductance, but half the holding torque.

I can move my axis perfectly fine with only 0.2A on the current motors which are rated at 1.5 , so I require very little force.
Chances are big that this motor will have enough juice to move the axis and will also be able to go faster in the end because if reasonably low inductance EMF, but due to the lower holding torque also more margin in the EMF due to rotation of the motor

I use the single shaft version of that motor in one of my printers. It will have more than enough torque for your printer. Plan on 0.8A current.

An axis will not move until it is homed (or the gcode to override "move without home" is issued). An extruder does not home.

An extruder will not move until its associated heater is above the configured temperature (unless the gcode to override "cold extrudes" is issued).

Both axis and extruder can be specified in G0 or G1, and if other axis/extruders are included in that same command, "coordinated linear motion" will occur (moving each at a speed that ensures they all reach their respective final points at the same instant in time.) So no difference there.

There are probably more differences and similarities. These are a few that came to mind.
