Since you say IQ is important for you, I would go for a Nikon FF camera and build a system together with my partner, where you can share as many ports and lenses as possible, e.g. the APS-C camera for macro and the FF for WA...
At the risk of this really going "off-piste" (if it does, I'll move the posts to a new thread), I was intrigued by your comment, Wolfgang, of using APS-C for macro and FF for WA.
I've been using APS-C (DX) on Nikon now for about 5 years having "downgraded" from the D800 to the D500. One of the advantages to this I found was porting WA. It's so much easier than for FF (FX) with no need for huge domes, correction lenses etc. Travel became easier, the patience and tolerance of my diving, non-photographer partner was restored - and life bobbled along happily. I slap on either the Tokina 10-17 or the Nikkor 8-15, a 4" or 8" dome and voila! No problem. IQ, to my eyes, is excellent - certainly for all the normal uses of the images (and I sell quite a lot).
But the one area that, maybe, I do think about with DX is macro. Sometimes some serious cropping is necessary and then I feel I miss the extra pixels provided by FF/FX. In reality I'm sure I don't REALLY need them but the thought lingers.
So I would have gone with FF/FX for macro and APS-C/DX for WA.
Your point on sticking with one system for downsizing is a very good one of course - but I was intrigued by your thinking on DX/FX.
As I say, if this conversation continues and others chip-in, I'll move this to another thread.
