I use a 1tb ssd for the os/apps with my raid5 strictly for storage. Kinda nice if the os needs to be reinstalled or I want to migrate the raid cluster.
That’s also a good option but I wouldn’t with 6 drivers personally. I have a 12 bay array with two pools of 6 each running raidz2. I’ve run raid 5 for a long time but have had one drive fail many times and always have mini heart attacks while I wait for the new drive to come in and the rebuild process to happen.
I do this for expansion. I can expand the pool three drives at a time instead of 6. But, I set it up knowing the risk with a single parity drive…and I’ve acounted for that with backups. 👍
The idea is going for raid5 so that should be around 100TB of storage, minus the OS and apps, etcs. But easily 80TB+ net storage.

but that means you need to give up a bay slot for the system sdd, right?
In my case, I use a PCI card with an m.2 slot for my OS drive. I lose a PCI slot, but I already had a few to spare.
That would probably depend on case, motherboard, and which (if any) pcie slots are occupied.
With that amount of storage I highly recommend RAID6.
I’d do a pool with 2x vdevs, each with three drives in raidz1
