Big Sur has some reported issues (eg monitor connections, bluetooth, wifi) on the new M1 systems though not on my M1 Mac mini base model. I'm not using bluetooth keyboards/trackpads or wifi and my oldish monitor is connected via USB-C to VGA and has no issues.
Backup before upgrading and you can then always restore if you need to do so
