I assume you have seen https://forums.freebsd.org/threads/a-solid-howto-with-bhyve-on-freebsd-14-and-windows-11.92236/

but just in case ... I really hate to answer a question with why not use 
this, but ... bastille works in a no-brainer fashion without or without 
zfs. In my setup FreeBSD is the base system and the other systems are jails 
under that. This may not work for you for reasons I do not see but maybe 
with will get a discussion going.
