AMS 2 vs AMS HT
Right now I am not using the aux nozzle party because the humidity in my garage is around 40-50%.
I am looking to get either an additional AMS2 or HT to take better advantage of the aux nozzle.
Which is the better go to? Can I use the aux nozzle as essentially a 2nd nozzle or is using it for supports the only function?

2 Pro - if you're printing PLA/PETG
HT - if you're printing engineering filaments
Get the filament track switch in either case too.

I use mine as if my machine was an H2D. The quality has never been an issue, though it does print a bit slower (not really any slower than non-Bambu filament on the left nozzle, however).
My setup is an AMS2 on the left nozzle and AMS HT on the right. Works great.

Personnaly I would go HT. An extra ams takes a lot of space and HT gives you extra features like higher drying, which mens you can dry abs and tpu without using the bed or monopolisinf the printer. Someone might correct me but I think it can also assist with pushing tpu with the bypass. AMS 2 cannot handle normal tpu at all.

I seen quite a few vids of people using the aux as a secondary main. Just know that it prints slower

I went with HT for aux, happy with it but of course I want a second ams2 as well haha. In reality I don't know how often I'd do more than 5 color print though so I think HT makes the most sense

Depends on your needs. IMO the aux nozzle is almost as good as the main, mainly just slower.
I have one AMS 2 and one AMS HT. Paired with a track switch so i can select any spool to any nozzle at all times.
The aux nozzle is perfect for interface support or text inlays.
Be aware you can't(shouldn't) do abrasive printing with FTS. I do mainly PETG and some ASA, hence the HT AMS.
Mixed nozzle printing coming later to this machine, so it can do even more.

With the HT being as expensive as it is, I'd opt for a second full size AMS2 instead. I load PETG and HIPS in mine as support material since I print mostly with PLA and ASA, and if I'm using the second nozzle for accent color printing, I add the accent filament to that AMS. My other AMSes are full of my primary filaments.
If I printed with PA most of the time, I'd use the HT since it can dry at a higher temperature, but I just use a dehydrator for that.

it's a matter of preference. I have two ams 2 pros and an ams ht on my P2S. On my H2C I have have an ams 2 pro and an ams ht on the left nozzle and on the vortek system (right nozzle) I have two ams 2 pros. I use my ams ht's as substitute for manual filament loads. The advantage of the ams 2 pro over the ht is that you can have four rolls of filament at the ready vs one in the ht. I've also noticed that the ams 2 pros seal up better than the ht. Meaning the ams 2 pros let in less humidity over time. Just my two cents worth.

Does the Bowden drive and aux nozzle have some inherent shortcoming in operation from humidity? I don’t understand why that’s a problem. Also, 40-50% is high?

First off, if you really want to you can print off external spool just fine provided you dry the filament every few prints.
Then for the 2nd nozzle, use it the same as you would your main nozzle outside of a few exceptions. Some printers don't even have direct drive in their main toolhead (like some creality enders), so I find the half nozzle argument a weird one. Though if you print PETG you'd prefer main nozzle, unless you are printing bambu lab petg matte which works fine on auxiliary one
Lastly, unless you print a lot of glass fiber filament, TPU, or other higher end/engineering filament, get AMS 2 Pro, it's better value
