Ok, went back a bit and changed my setup some to make it finally work. It was an issue with the parenting, which I thankfully was able to fix, so a big thankyou to you Arixsus. 
It now has:
A fixed over the shoulder camera (TPS)
A free rotate and zoom camera (TP). With limits on how far/close it can move.
A socketed First person camera using 3rd person body to simulate a true(r) first person.
There is some clipping with it atm in the FPS Camera simply because we used the sample body mesh provided, so that won’t be present when I swap it out for custom assets. But as a proof of concept, it works so I’m happy.
All assets shown are from the 3rd Person Blueprint that Epic provided. So special thanks to them for providing such great tools, and thanks to a friend of mine who helped me out quite a bit with it as well 
This was surprisingly made in under a week with about 7(ish) hours total of work, it was also our first time using Blueprint as well. Really awesome job you guys did with the Blueprint system. I’m loving it so far 
Here’s a video of it in action:
