What's your experience with Cloud witnesses? We use them here on all our clusters and I've wondered if there may be some communication issue with them that's causing some of our issues. That said, everything tests fine and I've never seen any indication of firewall or web filtering interfering with anything.

We don't use CAU. We patch just like you do. Every few months or as needed for any critical updates. A node at a time. Pause/maintenance mode/patch/unpause/disable maintenance/wait for disks to be healthy and storage jobs to complete/rinse, repeat. I seriously hate maintenance on S2D clusters. Microsoft and the hardware vendors really need to fix this. CAU works great on traditional failover clusters without cluster shared volumes. But CAU and WAC/OpenManage have never been consistent and/or safe enough for us to use on any of our S2D clusters. Hoping 2025 will be better, but I'm not holding my breath.

Did you ever figure this out? We're experiencing exactly the same symptoms you describe. Just started a few months ago.
