As Archicad can run on both windows and Mac without major differences, i think its not the software that should dictate your choice of a new computer/OS. If rendering is something that you want/need to dabble with, don`t go for a mac. Cooling, hardware limitation and the flexibility for future options is quite limited. I heard (cause i didn`t have a change to test ) that M1/M2 are powerful, but i don`t think they will be the most supported hardware for game engines/render engines. Besides that...if you will ever try to at least test another software besides Archicad/twinmotion you will be surprised that a lot of up and coming softwares are not working on Mac. I would only pick a mac for portability, but for a desktop setup, i would always go PC.
All things considered, you know better what suits your workflow.
