I think that would be a good choice!

We are discussing SS above. See other comments. And AMSOIL has been making Group III-based oils for ages, even back when SS was basically just PAO-based plus Group V.
Similarly, HPL uses Group III in many of their product lines, including the ones they use for the border patrol fleet. It has it place in many lubes, particularly if you aren't trying to blend a 0W-xx.
I know they use G3 in general, but it looks like SS using G3 is an assumption but was also presented as fact. I’ll just go back to waiting for a Voa.

It's an assumption based on the fact that they call out PAO in the SDS's for some of the grades (it would appear the 0W-xx grades) and don't for others (like 5W-xx and up, where you don't need it). Is this proof positive that they aren't using PAO in the grades with the less stringent Winter grades? No, but it's a reasonable assumption that if they are calling out PAO on the SS 0W-xx grades, the ones they aren't calling it out for is probably because it wasn't used.
And there was an EU MSDS that showed GTL in AMSOIL SS.
As others have said Amsoil has been using III's a lot. In fact in the Gale Banks video Dan Peterson who is the head of their tech department I believe said they like and use IIIs and esters. In reality you could make a mostly III based oil with ester and mPAO as a VII. Just as an example not saying they are.
Just keep in mind base oil blends can be complex and a mix/combination of many different base oils. That's been the game for quite some time.
The worst thing you can do is like an oil because it strictly uses one type of base oil. Don't get caught up in that.
"Regularly in some products" - per video (9:50)
"we do use base oils for sure in this group V area"
Amsoil has been known to like "proprietary" esters.

What are these? Made by someone at their request?
Good memory on that video. I had seen it before but didn’t remember that quote.
In their FAQ they used to state that they use proprietary esters. Know one knows that but Amsoil and their suppliers. One rumor years ago was Croda but I doubt that is right.
Maybe the ROC (Russian Oil Club) will do an FTIR if they ever get. You can identify ester/AN with that. Not type or quantity but presence of.

Also here is something interesting - weight deposit piston average for GF-7 is 4.6. dexos R is 5.4. In 2014 Amsoil SS scored a 7.7. They're claiming an even better score on current formulation that they thought wasn't possible.
Keep in mind this test is just testing the oil's ability to withstand high temperature for a long duration of time. It's not going to throw fuel, cold starts into the mix. The point of the test is strictly heat and time and how long it can resist deposits and oxidation in high temperature situation. (305F for 90 hours).

And it's run in a naturally aspirated, port-injected engine. A turbo under load would localize heating in the ring pack area but perhaps would be harder to control for this sequence, which is why they use the Pentastar. Its predecessor, IIIG, was run on a GM 3.8L V6.Also here is something interesting - weight deposit piston average for GF-7 is 4.6. dexos R is 5.4. In 2014 Amsoil SS scored a 7.7.

For sure and it would likely outperform any other oil in that test as well. Amsoil SS pretty much crushes every test you throw at it. Speculating of course but they do make it extremely thermally stable.
305F for 90 hours is a long time. Just think about that temperature and that duration. Then double it.
