You don't seem to understand equivalence (between sensor sizes).
f32 on fullframe is equivalent to f21 on APS-C. Would you use f21 on APS-C?
Again, there is zero advantage to having more depth of field with APS-C (vs FF) as you can always match the larger depth of field with FF by stepping down more.
When considering equivalent systems, you must take in account aperture, ISO and focal length.
I remember Klaus had written an article on equivalence with examples, but it seems the article is gone :-(
I recommend you read the DPR article on the same subject here to help you understand it better: https://www.dpreview.com/articles/2666934640/what-is-equivalence-and-why-should-i-care
Again, there is no inherent advantage to APS-C or smaller formats for macro photography.
The only reason why you might think APS-C is more interesting is because there is no equivalent lens available for FF.
For instance a 100mm f2.8 macro lens on APS-C would be equivalent to a 153mm f4.3 on FF. So yes, there is no such lens available for FF (yet) ;-) But this has nothing to do with sensor size.

Technically there maybe no advantage in APSc over FF for macro, but practically, there is, subject distance is a biggy, pixel density is another .. size/weight .. I don't care.....
I don't know if you guys have seen the work of Thomas Shahan's insect photography, it's breathtaking .......
his was then taking images using a super basic used Pentax K200 with a reversed ringed old 50mm lens (manual focus) and a basic flash ..... a magically calm talented man ........ enjoy!

For all except portraits and the occasional landscape I'll shoot APSc ..... to keep my distance from these capricious easily spooked critters and to have a greater DOF straight off the bat with a higher pixel density ....... and when you crop noise equals out .... many prefer M4/3rds to benefit from more of the same above reasons ....
You could apply the same equivalent reasoning to medium format for macro, but it makes little sense .....
I think macro is best adapted to the APSc sensor not because the equivalency theories are flawed, they aren't, but the suitability of FF has a few drawbacks that APSc adapts to more easily.
