I feel slightly stuck at some point, because it's too hard to get large quantities or iron to build new things, and fur is worth nothing...

You need to find an iron mine in the map first, and then you can put workers for irons.

Have you tried mining iron with villagers?

[S4M]

I don't know how I can do that, even though I courageously freed some mine from some monster or thieves (can't remember what it was exactly) a while ago.

On your village tab, you can assign tasks to villagers (such as mining).
