I don't know anything about the araine models.
I suggest the 737-400.  That is the top plane with a FMC for FS 2002.  Of course 767 PIC is the other top one. Even though it came out under FS-2000 it is very well supported under FS 2002. I still have FS-2002 installed and use it simply because of 767 PIC and my freeware Yannick Lavigne Falcon 50 which I discovered doesn't display correctly in FS9, the landing gear don't that is.  Shame you don't want the PMDG 737.  It has the most realistic FMC ever for PC simulation.  You might also consider checking out World Airliners which contain the PSS 747 and 777.  I still fly them to.  They are on special rack at most software stores, $19.99 USD or less.
