Just providing updates in case someone else comes across this in the future.
Changing out the NVMe cache drives (RAID 1) for a separate, single NVMe drive didn't help. The system was stable enough to complete the parity rebuild with 2 of my normally active ~15 docker containers running. I really started noticing a trend that when certain dockers and their associated dockers were enabled, the server would freeze. I later noticed the omada-controller docker was having odd issues with it dropping APs, unable to adopt, etc. and other containers also seemed to have some odd errors in the logs. I deleted the appdata folders for the troublesome dockers and reconfigured them from scratch.  This got those specific dockers working great again. The server seemed much more stable (been running all normal dockers for ~24 hours now which is unheard of lately) Some other docker containers were having issues with starting, even with the appdata deleted starting fresh along with re-installing them. I deleted the docker folder entirely (along with appdata for dockers I didn't notice earlier that were having issues), reinstalled all dockers, and everything is at least up and running now. Time will tell if this was the solution or not, but it's looking much better now than it has been in a long time.
