Basically, it should be aligned with physical sector size (reported in /sys/block/<device>/queue/physical_block_size). In my case it is 16K physical and 4K logical...256 is perfectly fine as sgdisk/fdisk internally decides.

I don't think ceph-deploy is particularly opinionated on this. Have
you tried using ceph-disk directly to see if the behavior persists?

For OSDs/disks ceph-deploy mostly proxies to a remote node with ceph-disk.
