Are they compatible? Could I use UFS for data exchange purpose?

UFS is available on all BSDs, including one doesn't support ZFS. So it's a better portable FS than ZFS.

Most Linux could mount UFS read-only out of the box, too.

zpool created on OpenIndiana can't be imported on FreeBSD 11.4 because of unsupported features. Can only import as read-only.

I presume by "data exchange" you mean: write a physical disk on ZFS implementation #1, then read it from implementation #2.

It should work, if you carefully look at what ZFS features the various OSes / ZFS versions you want to exchange with support, and use only the common subset of features. You can disable all the features you don't want when creating the pool.

In the old days, transporting physical media (often whole disk drives) between computers was often the fastest and most reliable way to transfer data. But these days, with ubiquitous virtual machines, there is often an easier option: Run the same (source) OS in a small VM on the target machine, and export the data via a network protocol (ZFS or SMB).
