Ethernet cables

Definitely worth it.

Mine weren't expensive, but also not cheap. The last two in the chain, from wall to switch, and to streamer.

Triode Wire Labs Freedom. Very happy with them.

Assuming you have a high-end system with the requisite resolutioncapabilitiesc: (a fine but important distinction) ….

Then the run-of-the-mill junk cables you get at STAPLES is a huge step down.…brittle, annoying digital “edge”, raspy, generally harsh and very fatiguing …full stop.

2nd thought based on actual experiences.

to max out the performance of quality audiophile Ethernet cables, think

- linear power supplies into the network switch,

- insert a step-up audiophile network switch ( yes…I used to be a big sceptic too) , and

- if your  sreamer/ DAC lacks an internal linear power supply, then plug one here too.

Ethernet Cables

"Digital is just 1's and 0's" is a good way to think about data trasfer (banks, nuclear weapons, photo downloads) but not streaming.  Streaming can's use FTP with error checking that will take whatever time it takes to get files bit perfect.  Streaming will just move on, play the song, with whatever bits it has been able to gather.  So good cables make a difference.

That said, with the stupid expensive cables you are paying for a lot of marketing, salesmanship, cosmetiic upgrades and perhaps not much engineering improvement. the sweet spot is probably in the middle somewhere.
