The multiple monitor thing is weird. The Mac Mini supports more than one, and the one display it DOES support is the Pro Display XDR, which has more pixels than two 4K monitors.
The M1 Mac Mini supports one external display on the Thunderbolt port and a second one on the HDMI display. There are probably limitations on simultaneous resolution and refresh rates. This iteration of the M1 was not designed to handle large amounts of I/O. I would expect a more advanced version (M1X/M2) sometime in the next 6-12 months. That iteration will likely support 4 thunderbolt ports, multiple external monitors and larger RAM limits. That’s the one that Apple would use in iMacs and the other MacBook Pros.
I do wish that Apple would go ahead and release a 27” 5K display for the current machines. The 6K is way overkill and there are no good options for monitors >4K. They are probably waiting for the new iMacs with a new design language to put out a matching monitor.
