I don’t expect anything but I did grab a good seat in the forward mini cabin of Y.
I haven't requested blocking for a few years. I don't know whether I still can, but my neighbouring seat is often empty if the cabin is not full. In the past, even if I did, if there was a reason, CX might still release my adjacent seat even if not full. It happened once for me (and I was a DM).
As the flight is on your birthday, there is a good chance they may upgrade you anyway if the upper cabin is not full... Happy Birthday!
