I didn't check my idle speed, but I don't think that has anything to do with your issue. 1000 RPM idle seems high to me, but my car doesn't have the same engine as yours.
I checked my idle today with my 1.5L. It was around 1k rpm.

After thinking about it, that makes sense. Smaller engines have less moving mass. Less mass means less momentum, so they require a higher idle speed. My brother's 1600cc motorcycle idles right around 1000 rpm.

I just plug in a small LED night light into the 110v and auto start/stop disabled, forever :).

I'm aware of this and it's not the cause
Mine did the same thing. There were some updates that for what ever reason did not automatically download to my trucks system. Took it in to the dealer and the service tech manually downloaded the updates and after that the stop/start would work as soon as I let off the brake. So I don't know if it was an update that dealt with this problem or if during the update it changed some settings on my truck. Anyway it starts back up as soon as I let off the brake now.

In my view If auto start stop is working correctly it's transparent. Since my battery was replaced I haven't had any issue's in it's operation.

Ah, gotcha.
I didn't want to spend $100, so I just added a $1.41 night light.

How in (select deity)'s name, does plugging in a nite lite effect the stop/start?

BTW, I truly have no idea why so many find this feature so egregious. I've been driving for over 50 years and don't see an effect on driving in any way whatsoever: other than it gets quieter for a few seconds. No lag, no adverse effect on the vehicle - it just works as advertises.

Having the nite light plugged in tells the computer power is needed for what's plugged in. Thus the alternator needs to turn so as not to draw down the battery.

I can see the light on this subject.

I went the Auto Start Stop eliminator route. Yes it's more money, but it doesn't run the 110V W inverter nonstop, and it's easily disabled or removed from the car (plug-n-play harness) if there's any debate on it potentially causing an issue.

You can use an OBDII reader with MS-CAN support and Forscan extended (endless 2 month free trials, no credit card required for trial) on a windows PC and just disable start/stop there too. That modifies the module from the AsBuilt configuration, but it can easily be restored to factory state from a backup, and I'd still prefer that option over running the inverter 100% of the time the vehicle is started...
