Hello and welcome. I think that many of your concerns/questions have been answered. It sounds like you are getting some sound advice and you're developing a good plan.
I am more a nano/pico guy, but if I ever go for a big tank it'll be really big tank. I think getting one larger tank between you is a better option than two smaller tanks unless you see yourselves parting or moving in the near future. OR you want to do two different types of tank? Aggressive/predator tank?
I'm sure you'll come up with a solid plan. Good luck and keep asking questions.

For sure. I get it. I hear that you can find good deals here on used equipment, but I haven't looked very closely.Its more of a price the more research I do on the 120 gallons just the price skyrockets compared to us each doing like a 30 and 40, 40 for me and 30 for him. I am pretty resourceful and I have a friend that is an engineer and could help me build a stand. Everything I look at though is all together and like 2,000+ money wise which is way more than what we would spend to at least start to cycle a new tank. I may be looking in the wrong places, I am going to be calling some local fish stores tomorrow (the idea didn't pop into my head until they were closed today) to see if I can find some around us that may have the bigger glass aquariums for sale and probably cheaper than online at very least.
I could also be looking in the wrong places. I have tried to look on my local facebook market place too so right now its more of a waiting game and seeing what I find out about the 120ish gallons. Right now price is the biggest concern there for getting it off of the ground. While I love the fish I can see in the 120+s I would still be happy to keep a 40 gallon with some clowns and my fire. So I think our 2 set up is still the best option right now, our dream is to one day of course GO BIG, what we were thinking is in the future we would probably upgrade to like a 200 gallon or something (at minimum probably a 5 year dream) and then one of our systems we would transfer into the big boy and the other we move to our bedroom or something. (I know they can be loud but he sleeps through anything and I always have ear plugs) There is also the fact that having a 30 and 40 to start would allow us to learn to really care for corals and make sure we got this. I could also consider a 75 of course to just combine our tanks gallons, which may be the play as we are doing more research anyway.
Right now I am just in a huge research stage so really trying to gather as much information as I can to make the best decision for us in a lot of different ways. I don't want to start with something so big and then we do terrible at keeping it since we are new. I am fine with 2 smaller aquariums to start, but then again I do know after reading like the bigger are actually easier. So really yea just getting all the information, researching, asking questions, re-researching, more questions....etc. Its my process but I really like to know what I am getting into before I jump in
I'm sure you'll come up with a solid plan. Good luck and keep asking questions.
