Out of curiosity, I just specced out the lowest-end Mac M2 Mini with 24 GB RAM and a 2 TB SSD, a 27-inch 5k display, keyboard and mouse. Getting 24 GB RAM is as low as I'd want to go given that I'm often using >60 GB on my current iMac. Screen grab from mere moments ago...
Is your current Mac an Intel-chip?
As far as I know the M chip architecture does not require nearly as much RAM as the "old" architecture, you may not need more than 8GB.
