Hey Fred,
in my VFD control cabinet I will use besides the VFD itself, (I already bought everything) the EMI filter that came with my VFD, the brake resistor matching my VFD, a Omron G9SE safety relay for which I have a red mushroom-shaped emergency stop button, a reset button to reset estop mode (important), and of course a short-circuit safe, high current 2-position rotary switch to turn the entire appliance on (35 A current, 2000 A short-circuit safe), a relay module for coolant pump and one for dust collection (the one that I plan to make myself in a DIN-rail compatible housing), a 24 V power supply for DIN rail to supply the relays and the safety relay, a 120 mm fan to the outside and a fan controller with temperature sensor, a 32 A MCCB, and of course terminal blocks, cable ducts and DIN rails. And stranded wire in different colors and sizes, and wire ferrules and ring connectors.
There is a thread in this forum where I listed what could be needed in a control cabinet:
I also put a IEC 60309 three-pin 32 A socket on the bottom of the case, so that it can be disconnected from wall for transport (my VFD is rated 24 A):
