Get one backplate. Get a singles wing. IF you need to go to doubles, get a doubles wing. Most doubles wings will work ok with a rebreather if you end up that far.
Why you would consider sidemount for scientific diving outside of a cave, I have no idea, but if for whatever reason you wanna be that guy, don’t get some rig that’s advertised for everything and sucks at everything. Get a dedicated sidemount rig.
I had no idea too other than it was a type of set-up and my brain tends to err on the side of 'what-ifs.' I think my SO would have a heart attack if I tried anything other than a large cavern or cenote, so small caves are out of the question anyways
