I did myself some math, and found some stuff
(this is all at 10% factory efficiency)
building any type of tank or plane and giving 100% of them gives .250 autonomy change per factory dedicated
infantry equipment gives .235 autonomy per factory
Artillery, AntiAir, AntiTank, and Support equipment give .246 (probably rounding error, and actually .25)
motorized infantry give .200
Convoys give 1.000 per naval factory, so they are more efficient until you get factory efficiency to 40+%
