Stem plants typically have roots at their base and will send out multiple side-shoots on the stem itself, for example Rotala rotundifolia.
(4 stems in this pic)


Some plants grow by sending out "nodes" or "runners", for example Hydrotocyle spp.
There are several nodes in this picture, AKA the long horizontal strands closest to the substrate where the stems/leafs come out of.
A lot of carpeting plants grow by nodes/runners.
When someone sells plants by the node, it typically means that you will be getting several leafs. How long of a node you'll be getting varies from seller to seller.

Nope. Buying plants with roots won't give you any benefit/head start IME, regardless of whether it's a low or high tech tank.

So you are correct it identifying stem plants, but people do not sell plants "by the node." The node is the little notch in stem plants that have leaves growing out from them. For example, your rotala picture has 4 stems, but every stem has about 7-10 nodes showing.
