Yup that is the stuff I use for the braided split wire sleeve. I did the 3/8in around each smaller cable and then once I got everything where I wanted it I used velcro cable ties to bundle them together and then used the 1/2 around the bunches of cables to better protect them.
The table pop up connectors for the power might work but I haven’t seen one with the number NEMA 5-15 plugs you would need to plug in all the power supplies. So for example you have one for the Auto drive itself, one for the power trim one for the primer express, one for the digital powder measure, one for the case feeder, one for the bullet feeder, one for the vacuum you will use with the power trim. That is about 6 NEMA 5-15 receptacles you will need just to power everything and if I remember correctly the primer xpress uses a two prong 90 degree plug (since its an AC to DC adapter) and not a 3 prong 5-15 plug like everything else so you will need at least one receptacle with a bit of space around it.
Generally the power trim that I have (its a dillon RT-1500 but pretty much the same thing) is mounted at station 5 or 6 depending on the toolhead I have to use (I have the 300BLK thin toolhead so certain stations need to be used). If station 1 is the case feeder station then this would be the 4th or 5th die location on the toolhead and puts you in the back of press just over the circuit housing for the autodrive. I ran my cables for the power trim along the left side of the autodrive base plate to up the case feeder support arm and then put a little slack loop in it so I can plug into the power trim and still have enough cable slack to allow for the up and down motion of the toolhead.
As far as the connectors are concerned the IO cables are always Molex 4 pin connectors with 18-24awg mini pins like this 4 Pin Molex Connectors
