Don't use zfs raid because there will be no benefit. You'll get the performance of software raid using CPU time, along with lost space for already backed up data. ZFS should work fine. A lot of the tuning on the wiki page isn't needed anymore, so it's not too bad. The biggest thing to be careful with is upgrading your zpool, every so often your boot blocks may need updated and if you forget, you can't boot. You won't upgrade your pool often of course. Reliability shouldn't be an issue, it's FreeBSD. ZFS will make it easier to play around with jails, have fun and create a 1000 node beowulf on one system.
