Couple of things to consider when choosing hardware.
GPU operations:
Flyover, Zooming, and Panning
Feedback graphics( snapping, highlighting, etc.)
Shaded rendering
Rendering plug-ins such as Redshift / TwinMotion / Lumion/ Enscape
Vision – 2022SP2 runs natively on M1's
CPU operations:
Renderworks
Hidden line
Plan drawing
3D modeling (mix CPU/GPU)
Viewports (Mix CPU/GPU depending on type of rendering)
Even though most of the Rendering in Vectorworks in done in the CPU, I will recommend you to stick with the Apple M1 Max 16" - with the 32GB.
