Sewage Ejector Pump

Paper towels, baby wipes, and facial tissues do not break down easily and should not be flushed into a sewer ejector pumping system. Toilet paper tends to break down quickly and should not be a problem.
Mixers are sometimes used on large municipal pump stations where restaurant grease floats to the top. You can purchase mixers with either a compressed air or an electric propeller as the mixer power.
You mention "sewage ejector". That implies a small residential sump pit. Mixers will not usually fit in these small pits.
You can try to adjust the float so that the lift station water level drops lower. That will leave less residual water in the pit between pump cycles.
You can also add some concrete fillets in the pit bottom so that the bottom of the pit slopes toward the pump suction.

If you have to live with that situation, consider adding an air sparger mixing system.
