> FreeBSD jails don't have a one-command way to install a preconfigured jail for a specific service

FreeBSD does have that tool, its BastilleBSD: https://bastillebsd.org/

For example, this is the Bastillefile for running consul: https://gitlab.com/bastillebsd-templates/consul/-/blob/maste...

To add on, CBSD may also provide of these functions. So there are options.
