Dual Monitors on M1 Mac mini

Just received my maxed out M1 Mac Mini. And am struggling to find a solution to run my dual 4K monitors, and am looking for solutions.

The first thing I tried was 2 new HDMI 2.x cables, using the Mini's HDMI port, and then purchasing a new Thunderbolt 4 hub that had a HDMI 2.x port.

However, if the Mini goes to sleep, when the monitors turn back on, the Display Arrangement and scale settings get all screwed up; they'll reverse right/left position, and go from the default full resolution to something weird like 1280x720.

I haven't seen anything on the Interwebs about successful dual monitoring on the new M1 Mini, so looking for anyone who's found a solution that doesn't take up all the ports. My next trick will be to purchase a Thunderbolt to dual DP (DisplayPort) hub and see if DP is more stable.
