Thanks ! That was the answer I was looking to get confirmation on :).   I have some static route which will be using aggregate Label (VRF Table label)...
So we may need to force all the prefixes (including the static ) to use  per prefix label.

From the SPOKE perspective the routes imports will be / should be from the HUB VRF only. My initial concern was of hair-pinning of SPOKE TO SPOKE TRAFFIC  from the HUB VRF.

You addressed your concern perfectly, as long as you do not use table-label solution, the packet will go all the way to the CE, however you still need to maintain configuration in CE which forces packet to  FW instead of returning back to PE.
So once you have the config, double check the VPN label is pointing out to CE, and you're golden.
