There's also the Standard Entry A2SE which says sustained 800 but doesn't have the VPG800 rating.
I did scan dclark's thread about the bottleneck and seems like nothing uses 4.0 yet. So, the advantage would just be faster offloading. SE is still VPG200 but should match sustained of the older cards.
VPG200 even covers the highest requirements on the Burano with ample headroom.
EDIT: comparing prices, I would skip the SE and just go for AE since they are the same and the AE also has the DAPS feature as the PRO. The PRO would only be necessary for a camera that uses CFe-A 4.0 releasing a few years later (VPG800).
The PRO does have an interesting feature:
"DYNAMIC AUTO POWER SAVE
The NX-A2PRO series is equipped with Nextorage’s proprietary “Dynamic Auto Power Save” low power consumption technology. It effectively suppresses power consumption during high-speed continuous shooting and video recording, as well as the rise in temperature of the card itself. Compared to models without this function, power consumption is reduced by up to 89%, and thermal throttling* is suppressed to enable stable, long-time shooting. 3
* Thermal throttling: a control function that suppresses the transfer speed to prevent thermal runaway"
EDIT: The AE series in fact does NOT have the DAPS and it was a typo on BHPhoto's website which they will correct now.
----------------------------------- TLDR-GPT
Host limit: a9 III = CFexpress Type-A 2.0; ~530 MB/s in-camera write. Extra “4.0” speed only for offloading.
VPG: 400 is enough. Nextorage A2AE and Lexar GOLD both qualify.
Power/Thermals: Nextorage A2AE (and A2PRO) has Dynamic Auto Power Save → small heat/runtime gain.
Ruggedization: Lexar GOLD = IP68 (dust/water). Nextorage = no IP ingress rating.
Best picks: A2AE (value + thermals) and/or Lexar GOLD (environmental protection + long warranty + both VPG400).
A2PRO: Skip for a9 III; consider only for future faster hosts or extreme sustained heat.

EDIT: The AE has it too, but Lexar Professional Gold, Prograde Iridium, and Angelbird Pro also mention it. The Lexar PG is rating IP68 with a 10-year warranty (I know of Delkin's great warranty too but I was left with the Lexar and Nextorage in terms of speed/feature ratio).
