Debian release cycle is almost exactly 2 years, much like Ubuntu with some deviation.
You can install Debian, on ZFS if you want.
Now speaking of corporate customers, well that is not a great argument, as even more users use Red Hat, which is IMO an inferior distro.
What is good about Debian, however there is a very little chance of it disappearing one day, or dramatically switching to snap-only or some other nonsense deviation. In a way, it is even safer for corporate use than Ubuntu. This is why it is used in Google (the used to run Ubuntu before on their workstations).
