Ideally you would connect a non-USB mixer to the stereo line-in of the Mac and record from the line-in. You would monitor directly in the mixer. But you don’t seem to have a line-in. What is the Mac model? See Apple menu > About This Mac… .
The 2012 MacBook Pro 13" had one connection you had to reverse in Mac System Preferences.

My 15" starts dividing up the world into Input and Output menus, but I don’t think you have that option. You get to pick one. Once you select Input/Recording, you should be able to pick the same thing in Audacity Device settings. Built-In Input??
A friend of mine had one, so I can’t look up the exact settings.

You should not be using SoundFlower. Full Stop. Switch to Input or Record in Mac Preferences. When you do that, it should be possible to play music in your mixer and see it in the Mac bouncing light sound meter.
Again, I don’t have one of those in front of me so this is a little magic. The Mac has to know about your mixer before you even start Audacity. Audacity gets its sound from the Mac.
If so, the Sound Preferences Input and Output tabs had a “Use audio port for:” dropdown. I don’t know the icon that was used on the machine for such a reversible audio port. Was it headphones, and no different to latest Macs that have only a TRRS headset port?
If you have that menu, choosing “Sound Input” there should change the Input tab from “Internal microphone” to “Line In” (which is what you should be recording from):
If so then the reason your input cable is not seen in Sound Preferences may be because you don’t have a TRS to TRRS adaptor, but if this is the reason then that input simply isn’t suitable for high level RCA outputs from a mixer. Even if Line-In could play the input through the Mac, the sound will probably be distorted.
