I use a vegetable based coolant and waylube from Oemeta. I have no idea where you can buy it, because they donate it to us. No smell, no growth, very irregular usage of the machines. The only difficulty I have is that the waylube gets a little sticky after sitting a few months, and the Z axis on the Mori lathe will alarm when first run. I leave a little cover off the side and manually turn the Z ball screw a half turn and then everything runs fine. The Oemeta waylube and coolant are completely compatible, so no need to skim any tramp oil. We use flood in both the Mori DuraTurn and Mori NVX. I put the coolant in a hand spray bottle for use on the manual lathe, mill, and bandsaw.

The mill I have has flood coolant but I've never used it. Read about bacterial growth and smell. No way to easily add an expensive disk oil separator. Possibly a belt oil separator into the fill hole might work. Thing is the machine shop may go unused for months at a time.
