Maybe you have been lucky, but for me freebsd-update sometimes drops
into interactive mode to resolve conflicts in /etc

You are right, in my test setup py36-Jinja2-2.10.1 is already a
requirement for sysutils/ansible.

A good question. Let me remember the most tedious tasks.
1. I already distribute some configuration files (like
squid white- and blacklists, hosts.allow, sysutils/vm-bhyve templates
etc) with net/rdist6. I may replace rdist by ansible if it's more
flexible (rdist cannot edit files, only replaces if newer).
The "copy", "lineinfile" and "blockinfile" modules are for that, right?
2. Installation of packages (from the single repo I keep) and keeping
them up-to-date. In jails too.
3. User and group management certainly. In jails too.
4. Creation/destruction/configuraton of a) jails and b) VMs in vm-bhyve.
5. The management of Let's Encrypt certs (I use acme.sh currently). Do I
even need ansible for that?
