I never know where to report bugs I find. I'm posting this here in case someone has the lightbulb that says 'heres what he doesn't know/what he's doing wrong'.
I discovered inadvertently that what I believe is a flaw that exists in the Group setup. When I group 2 plugs, with simple on/off the type is set to become 'Group Bulb Dimmer (group 2.1) in the Device list under 'Type'.
This is a problem with Alexa. Alexa uses this device type to categorize the device being 'discovered'. Pre-built automations with Alexa - such as 'Alexa, Goodnight' automatically turn off all Bulb/dimmer devices.
I tried modifying the Type of the group to other choices, and was unsuccessful. Only Group Bulb Dimmer works. While I agree the norm of groups is a Bulb set, there needs to be a type for 'Group Plug' (and logically it follows there should be a 'Group Switch') so that external sources integrate better.
As a workaround to this, I'm not sharing these broken groups with Alexa, but handling the grouping manually at the Alexa side which is a royal PITA.
Of course, my gut tells me I've just missed something obvious and I'm about to take a beat down
