Yes, I see Original Graves as an old-school gentleman, but one that is smart enough to understand Queenie for what she is - a mix of humility and flapper autonomy, strong at times and vulnerable at others. While Queenie can "read" his decency, but also his tendency to wall himself in work and his public persona. They do each other a lot of good.

I know many authors assign Teacher!Dumbledore to Dumbledore, but my own headcanon is that, when asked to direct a House, he asked for Hufflepuff. Post-Ariana Dumbledore tries to cultivate humility, loyalty and collective spirit, and is wary of anything to do not only with power, but with fthe ethics of fighting. I rather liked the idea of him enrolling Fawkes on Imbolc Eve to comfort a bunch of kids, some of which - like Newt, if we read between the lines - must have been pretty homesick.
