I would cordially disagree with the notion that it is "advantageous" in some way to run a 64-bit CPU in 32-bit mode. This is a backward compatibility mode.

Far better is to run the OS in the native addressing-mode of the underlying CPU, and then, if necessary, to let that OS run 32-bit applications (necessarily using the same hardware compatibility mode, this time for its intended purpose).

If you have "old" hardware, drivers, etcetera that don't understand 64-bit, then, by now, you should replace these things.

I completely agree. This isn't a discussion along the lines of init systems or window managers it's a simple fact that FS bit arcitecture was a re-design of x86 with forward-compatibility in mind.
Modern AMD64 arcitecture chips are better than the older x86 chips and to take advantage of that one should use code compiled for the AMD64 arcitecture.

There have been number of 32 versus 64 bit threads on LQ. Not sure any have been solved.

The OP has a good opportunity right now to try both and see if one or the other has a best use.

Since we don't know what they are using this system for we can't fully guess.
