I think you may be misunderstanding. W680 is a workstation chipset (the consumer equivalent would be Z/H/B prefix), and Intel considers Raptor Lake-S + W680 as an Entry Workstation, which is why it’s being suggested here.
It’s also important to note that both Xeon and Intel Core shares the same core designs, e.g., both Xeon 4th Gen and Core 12th Gen are using Golden Cove. Many vendors also provide this combination of W680 and Intel Core as their workstation. For example, HP Z2 G9, Lenovo ThinkStation P360, Dell Precision 3660. These systems are properly certified by software vendors such as Dessault.
From my experience, the presence of ECC has more to do with the stability than the CPU itself (Xeons are not Errata-free, and Intel publishes a list of CPU bugs and workarounds all the time). Workstation motherboards are also known for not doing something too far out of the spec like pumping excessive voltage everywhere, and that contributes to the stability (although overclockable Xeon is now a thing) than whether it is Xeon or not.
If you really want to go with Xeon, and speed is not the priority, then Xeon-w 2400 series is a good choice. But do note that it has quite a lot less single thread performance than the current consumer platform with W680.
