Erythritol as a NNS is claimed/marketed not to effect the gut biome, indeed to pass through the body unmetabolized.

This is a bit more complicated, it is not really metabolized but it does have a big impact because it is absorbed by the gut and also change bacterial populations... https://academic.oup.com/advances/article/10/suppl_1/S31/530...

According to the article in the link, erythritol doesn't change bacterial populations.

[ta988]

Yes that mean that in their experimental setting it didn't change. Doesn't mean it doesn't in other conditions or when measured by other means.

generally any alternative sugar that isn't metabolized by you is metabolized by bacteria

I could see how this would relate to sugar cravings. Or sweet craving. More and more of a certain kind of bacteria lines the gut and grows better in it's main food supply. So what breaks these NNSs down?
