Also, my research concluded that expansion valves were superior to orifice tubes, but due to cost, orifice tubes are used in most cars. Now I am hearing the opposite.

You did not get conflicting information from ME.
You got ' R12 replacement ' recommendations from people SELLING that kind of stuff...
Use R 12 for best cooling and least load on your system.
I am not selling anything.
The choice on TXvalve and orifice involve other things designed into the system.... both work with proper systems around them... so you need to go with what you have.
Of course... it is YOUR car and you can use whatever you want to...
