OK, I got the replacement drives: WD40EFRX and packed and sealed the bad ones: WD30EFAX.
Currently I have my backup/toy system at home connected to the production system via Gbit and replicating all my data. I intentionally offlined one drive of the target pool (WD) and intend to resilver tomorrow when I have some terabytes to swap around.
What was a real surprise and keeps me thinking hard at the moment: the WD EFRX are silent! Like in "no contest", specifically when compared to my Toshiba N300 I run in my production system. If the resilver tomorrow goes well I am really tempted to do the one-drive-at-a-time dance to get the WD ones into my home office and use the Toshiba ones for off-site backup.
OMG! What were they thinking? After a couple of hours I'd say, these drives (EFRX) are just great value. Whoever came up with the idea to ship an inferior product, not being transparent to customers, just to increase the margin ... deserves the fate of the Sirius Cybernetics Corporation's marketing department.
I'll add the smartctl output for completeness but do not expect any surprises here:

I think rotational speed has a lot to do with that, 5400 vs 7200. I'm a big fan of the "slower" WD NAS drives at 5400, I like quiet and cool.

Honestly, I had no idea about the rotational speed. At the time I bought the Toshiba drives our company's default supplier (ALSO) did not offer anything I found attractively priced (for a hobby setup) and at Amazon the most frequent problem with disk drives seemed to be inadequate packaging of OEM products according to the reviews. I picked the N300 because they were reasonably priced and sold as a "retail product" with a complete shiny package around each single disk. No kidding, that was my main motivation. They have not failed me since, but they do make themselves noticed ;)

I have a WD Red 8TB with EFAX in the model number
I've read this only effects 2-6TB drives...
Luckily the rest of my 8TB are Ironwolfs
I paid a lot more for the WD Red drive to possibly get an inferior not fit for purpose SMR drive
Have Fun

There's no reason to believe the WD80EFAX is SMR. From the platter DB:
Check the R/N! If it's still US7SAN8T0, then that's still a HGST DC HC320. Platter size is well below 2TB. If this was SMR, we'd expect 4 platters, 8 heads. The platter size DB is really helpful, when trusting manufacturers is hard. It's here: https://rml527.blogspot.com/2010/10/hdd-platter-database-western-digital-35_9883.html
To a normal person there is every reason to believe drives with EFAX drive are SMR, 2-6TB drive like this are larger drives with the same naming are CMR, this is confusing, you have convinced me I'm fine
NAS drives should be able to support a rebuild in a timely manner, I imagine a vdev with many Archive drives or WD Red so called "NAS" drives could fail completely if the inferior drives are dropped from the vdev resulting in data loss, or a rebuild time is so long you data is at risk for months
WD need to be punished, but not destroyed
I only see Exos, Ironwolf and NVME drives in my immediate future
Have Fun

Is there a reason why they would not list Gold drives in that doc?

If I were to guess: That post was aimed at consumers, and talked about consumer / prosumer drive lines.
WD likely didn’t want their data center drives - Gold and Ultrastar DC - anywhere near this mess.
Data center customers will buy SMR - see HGST’s HM-SMR line that you can’t even buy unless you are web scale - but they’d never touch a DM-SMR drive. Predictable performance is the name of that game.

It completed resilvering no prob in reasonable amount of time, but it just failed during a long test. Replacing with a Seagate.
