Toni, your example simply shows that a 85mm f1.8 fullframe lens mounted on an APS-C camera acts exactly as a 130mm f2.8 lens would on fullframe...
It's a consequence of the crop factor.

Talking about macro, if you really want to carry the lightest/smaller gear, then you should strongly consider an MFT system such as an Olympus/OM body with the 60mm f2.8 macro. This lens is super tiny.
Such a system would be equivalent to:

- 120mm f5.6 on fullframe
- 80mm f3.7 on APS-C

Even greater gains ;-) (at the cost of equivalent aperture obviously).

I was just suggesting you keep the macro lens, anyway, I use mostly full frame except beach and pool shots where I use Olympus Tg5 (because it's waterproof)
APS-C is just a backup system when I don't want to lose time  swapping  lenses and prefer using 2 camera bodies instead.
you can do whatever you like  
When it's about shallow DOF it's obviously full frame myself I use RF 85 and 35mm primes and dropped APS-C primes. For the rest both are good, I don't shoot macro but I don't like very lengthy  Minimum Focusing Distance. And that's  why I sold EF85mm and bought RF85mm, and that's why during 5D days, I used to  prefer 100 macro for portraits over 85f1.8 .
 Of course minimum focusing distance won't change between APS-C and full frame but angle of coverage will.
