Before I write something that's already been done, are there any built in
utilities or tools that can tell me if it's safe to reboot a host? I'm
looking for something better than just checking the health status, but
rather checking pg status and ensuring that a reboot wouldn't take any
undersized PGs offline. Thanks.

Yes you can!
Find OSD's by bucket, like `ceph osd ls-tree <host>`, then check this
OSD's is safe for maintenance `ceph osd ok-to-stop <osd.n>`.
