which network cable

It is your experience and I respect it.
But what do you mean by “fail”?
You mentioned over many years but some elaboration would be helpful for everyone to understand what happened. Thanks.

Fail equals stopped working. The cables would not send signals. The splitters and switches stopped working. I have bought many things from Monoprice to try a save a buck for the last 10 or so years. The time and frustration trouble shooting in the end was not worth it. Nothing was DOA, but failed at some point after a few years. Oh, forgot, bought a drawing tablet from them for my daughter. Driver software installation was very difficult to install and was unstable. Ultimately found a 3rd party driver which was more stable. That has been my experience so I'm done with them. I hope you and others have better luck

Might it be a good alternative to instead of a decent ethernet cable place a standard cable with the addition of an ethernet isolator? I ask out of 2nd thoughts on giving the best unpolluted ethernet signal to my streamer. It is beyond my current knowledge to know if network equipment is by its nature already equipped with transformers for separation and hence filtering undesired static. If so, this alternative might be just a double dip and I'd be focusing on the proper cabling.

Something like this.

Network Isolator emosafe EN-70e • EMO Systems GmbH

They claim besides adding safety that it lowers somewhat the noisefloor.

I googled around on electrics of RJ45 ports though -as I’m no expert in this matter- but it occurs to me that such isolation transformers, maybe in a somewhat lower grade that the device linked above, seem to be already part of the Ethernet specification, so then indeed such a device would be a double dip.

Here's the definition of an Ethernet isolator:
It disconnects all the electrically conductive connections between the connected network peripherals and the connected device, and typically provides protection against DC and AC voltages of 4 kV and greater.

Not sure that's going to help in an audio application. You really want to block AC leakage current and CMode noise. You're correct that good RJ45 ports use isolation transfomers. The EtherREGEN's are particularly good: "RJ45 module that utilizes 12 transformer cores in each port (most Ethernet ports have 2~6 cores), and ground their center-taps through capacitors in a way that blocks port-to-port AC leakage currents."

A Shunyata Alpha Ethernet cable has a CMode (common mode) noise filter specifically for it's use in audio applications. I can't over-emphasize the importance of using a audio-grade Ethernet cable for streaming applications.
 
Something unique form top range - David Laboga Custom Audio Ruby Ethernet. This cable aren't typical Ethernet IC - it has no CAT standard topology, but works and sound great, completely different than Synergistic Research Galileo SX Ethernet, but this is the same quality level.
