So I don't sacrifice too much speed, but still get a torque boost.
No I'd stick with 10mm pitch @ 1:1 has you'll be speed limited with 24V so the extra lead of the screw will help here. With 3Nm motors torque won't be an issue really unless really heavy gantry or running 2 x screws from one motor.!!
