Yes, I have used FreeBSD and ports. I thought OP's message implied that there are 3rd party applications that are available exclusively for FreeBSD.
For a while there, one such feature was ZFS. I know ZOL is a thing, and the pool versions are the same, but I'd bet ZFS on FreeBSD is still more stable/standard than ZOL. (It's been a while since I tried to learn the differences between ZOL/ZFS under FreeBSD so that could be out of date)
ZFS on FreeBSD does not fit the definition of 'third party'.
In fact, many of the packages are exactly the same from the same upstream. The differences are freebsd specific patches to fix small (like enabling or disabling different compile flags) or large (for example in the case of gnome or openjdk which requires effort to port) issues, but the packages are all there.
