In my setup, I mount the /home directory using nullfs with the nocache option to facilitate access for certain jails. The primary reason for employing nocache is due to the implementation of ZFS quotas on the main system, which do not accurately reflect changes in file usage by users within the jail unless nocache is used. When files are added or removed by a user within jail, their disk usage wasn't properly updated on the main system until I started using nocache. Based on this experience, I'm confident that applying nocache works as expected in your scenario as well.
