For simplicity I only talk about Espressif's SDK+AT firmwares..

OK, that's interesting..

I was sure the non-C1 vs C1 are hardware properties.

BTW,
there are situations where we cannot really choose.
For example,
If you have a 32Mbit module/board,
and you want to Flash it with ESP8266_NonOS_AT_Bin_V1.7.1,
then inside the ZIP file, in the bin\at\ folder, you will see this:

There's only a 1024+1024 option,
no 512+512 option,
so this means that some Firmwares dictate choosing only the "-C1" option..

Yes correct - I believe there have been a few posts in the github for the NonOS SDK about the latest AT firmware only supporting 1024KB sized partitions.

OK.
Thank you so much for your help with this.

I will now flash 3 ESP8266 boards that I have..

this means your module of flash installed, and you can choose to set that up 512KB partitions
