best network switch configuration for audio

Thanks kijanki!
"In your case Ethernet network transfers data and not music." Quite right. What I am concerned about is the data that contains the 2 channel music info as opposed to the data that carries all the other info going over the network.    
 "I would use dedicated shielded Ethernet cable" Roger that also. All "horizontal" cable will be Blue Jeans CAT 6 (or 6a) and kept away from AC circuits. That will help with RF (don't want my ethernet cables acting as an antenna).
I mainly was interested in insight on 2 other concerns:
1)The effect on the system and on streamed 2 channel SQ with multiple long ethernet runs vs fewer long runs with switches and patch cords at points of use.
2)any advantages, any techniques, for isolating music data stream from other data streams, especially those likely to have "noise" from power supplies

Thanks all. So to summarize to date, it sounds like consensus is that:
1) bandwidth is likely not to be a consideration. Seems that way to me also. Haven't had problems yet and internet download speed is typically 150 - 170 Mbps.
2) As long as CAT 6 or 6a is used for long runs, my fairly revealing 2 channel system (CAPS microZuma server, PS audio DirectStream DAC, Magtech amp, Soundlab M-1's) is unlikely to suffer audible RF problems.
3)Having non 2 channel components (pre/pro, TV, DirecTv receiver, etc) connected to the same local switch as the DAC is not likely to adversely affect SQ.
4) wall wart (low quality switched mode power supplies) powering the local (or central) switches are likely to affect SQ. Running these on a different circuit will help isolate that. Hmm.
 I can do that since I put in a separate line off the electrical service entrance panel to a Torus panel and have 5 circuits off that dedicated to the HT room. The DAC will be on one of those circuits. I also left the original outlets in the room which come off the house subpanel. Local switch can be off that circuit.Problem may be that since those house circuits have a different ground path (but all grounds ultimately do tie back to the service entrance panel) there is a possibilty for different ground  potentials in the two circuit systems which can then interact via the low voltage connections (in this case ethernet) between components. I know this is a real phenomenon through the work of Bill Whitlock and Jaime Fox, but not sure how big a deal it might be in this application. Sounds like using the house circuit might be the first thing to try though since it is so simple.
I suppose other options might include linear power supplies for the local switches, ethernet filters, wire to fiber then fiber to wire  transitions before the DAC.....All options to occupy future cold winter days inside.
I just thought - does anyone make a non megabuck fiber switch and is using that even anything other than the deranged musings of an OCD audiophile?

Hah! Multichannel quad DSD - wouldn't that be nice! I can only imagine. Maybe next year:)
Thanks again for your input, it was quite helpful. Happy new year!

Bloviate on, ulmerc. That was a great post - understandable, helpful info based on real life experience, not just conjecture. I'll be using some of this info for sure.  To clarify, though - when you say PoE switches can be noisy, do you mean sound noise or electrical noise?
