It doesn't seem to be one problem hat causes these issues.
Homing axis and return to the part to go on printing seems to be related to "minimum layer time". A parameter you can set in your slicer. But then again it would be a regular thing.
Retracting the filament, while it shouldn't could be caused by running hotend/thermistor and stepper wires along each other. ( EMI problems )
It often shows up, with wrong or jumpy thermistor readings, while the heater is in PID mode.
Keep the thermistor wires separate from the power cable and twist the stepper wires, if possible.
Another source of problems could be the 5V regulator on your controller. Check the voltage. if it is below 4.6V, that can cause all sorts of problems.
