Interesting you mention jumping spiders, I just saw a rather interesting video talking about exactly this and includes some interviews with scientists involved in some of these experiments [1]. One interesting fact I learned is that they have a sense of numeracy, and can distinguish between one, two and three-or-more objects.
If you read fiction you might find The Children of Time to be interesting. It follows the hyper accelerated evolution of jumping spiders to a sentient species that eventually has to coexist with humans. It leans on a lot of fact about jumping spiders and uses it as a jumping point to what their societies might look like if given the chance to evolve as the top predators.
