v14 is pretty much just a version bump without much usable
functionality change on FreeBSD. I don't think upgrading to it will
have any practical impact. Given that pool version upgrade is a
one-way process, I'd wait until v14 features are really needed.

In any case it would be prudent to change only one variable at a time
during experiments.
