I'd rather have huge terminals though =\ so much easier to just deal
with bare wire that gets screwed in.

think you're doing the same right now. None of this is objectively a
big deal.
I have done something similar to Gino on the LTE deployments where
Telrad used a 4-wire connector. I.E.: Use a surge suppressor or other
connection point to transition from 4 wires to 2 wires. You do have to
up-size the two wires appropriately.
I can't speak for Cambium as to why they chose a 4-wire connector....but
use a DC wire size calculator and consider the more extreme cases with a
tower deployment. 4-wire lets you reduce the wire size two steps
compared to 2-wire. So 10ga becomes 14ga, etc. I'd guess they were
trying to avoid putting huge terminals on the radio head.

The issue with 4 wire:
1) It's stupid -- whatever I can do with 4 wire I should be able to do
with 2 wire.
2) The connectors are extremely small, to the point they are hard to
work with and more things to break.
3) It's not standard red/black, so more chance for someone to wire
something up wrong
4) More connectors to go bad. And small wire on each of them. More
things to break down the road.

What's the issue with 4 wires?

We are using Ubiquiti SM Bi-Di SFPs... work great.
Fiber, I'm using fiber from Benton Cook at CTI. Lanshack also sells
pre-terminated outdoor micro armored.
Power -- is a pain in the backside. Talk to Benton at CTI... he's
got some cheaper Belden cable... but seriously, Cambium needs to do
away with the 4 wire.
You will need to buy special glands for the fiber (PG-13 or
something is the part number).

What are you guys using for fiber and power cabling to the 3GHz
450M? Is part C000065L008A the correct number for the single mode
SFP and does it come with the gland and licenses? Putting up my
first one and I want to make sure I have everything in-place.
