Over the course of the 18th century, those trading networks - and use - expanded dramatically. Coffee and tea consumption grew rapidly in the first few decades of the 18th century in England and the Netherlands (where we have the best information/data), even in areas that were fairly backwater (trade wise). A comparison between a coastal village and a fortress town in the Dutch Republic found comparable adoption of tea/coffee, with both being commonplace by the 1750s even in the ranks of the working poor.
Anne McCants summarizes the spread of these commodities over the 18th century thusly:
Naturally, we find them first and most prominently in the urban maritime communities that facilitated their arrival, but their diffusion into rural and interior locales was often remarkably rapid. Even more surprisingly, the presence of many of these so-called luxury goods is well documented down into the ranks of the working poor by the middle of the eighteenth century. [...] European demand was fueled not only by the rich [..] but also by the much more numerous lower and middling classes of Europe's multitude of urban centers, followed by their rural counterparts.
Shifting over to France, perhaps the most prominent of colonial products was tobacco - which was under a state monopoly for most of the 18th century (until the Revolution). The use of tobacco was extremely widespread across France - with millions of pounds a year of legal tobacco being spread to ~10,000 tobacconists by the middle of the 18th century. On a per capita basis, this is similar to the reach of modern 'bureau de tabacs' in France today - with the mid 18th century having 1 tobacconists for every ~2500 people, and 2019 France being at 1 for every ~2800 people, to give an idea of the reach.
However, this was matched by a flourishing illicit trade that affected rural areas just as much as urban ones - with the most visible ones being bands of armed smugglers commonplace in several regions of France, as well entire villages banding together to resist and scare away official agents. Smuggling would come in either large forms (primarily through particular border regions or the northern coast), or in smaller shipments that were available throughout France, in the same way that people from all walks of life would participate in this illicit trade (which made up between 1/3 and 2/3 of all tobacco volume in France).
Hopefully this helps to answer at least part of your question - these are the examples/trends that I have generally been aware of. Unfortunately I do not have information on Germany or Spain to add.
