I use four 8-channel signal snakes and a speaker snake. The cables and XLR jacks on all of the stage boxes are numbered and color-coded; XLR cables and DI's are also color coded:
Drums = yellow;
Vox = red;
Backline = blue;
Yellow snake runs from FOH to drums. It is stored in a "yellow" carry case with the drum mics and the drum loom that connects the mics to the stage box/snake.
Red snake connects downstage mics to FOH. It is stored in a carry case with vox mics and mic cables.
Blue snake connects backline instruments & vox. It is stored in a carry case, along with XLR and 1/4" cables, several DI's, and backline mics.
I also use an A/C umbilical to which several two- and four-gang Edison boxes are connected.
The first thing I do on stage when I get to the gig is position FOH cabs, stage monitors, amp rack, cab snake, A/C umbilical, and stage snakes. Gaff tape secures snake cables to the stage. Separate, color-coded, snakes and cables make it much easier to delegate/communicate when I have help.
Next, I run & gaff speaker cables. Then, I set up the drum loom and mics, followed by instrument DI's and mic cables.
As each band member sets up their gear, they are responsible for connecting their instruments and mics to their respective snake boxes.
While they're doing that, I'm making all of the connections at FOH.
When I see a Yellow cable labeled #1, it's kick drum; Red #1 is lead vox; Blue #1 is bass, etc.
I also use a snake to send signals from FOH to the on-stage amp rack that powers stage monitors, FOH cabs, and subs.
If I were using a separate monitor mixer, I'd run a 32-channel snake with several returns from FOH to monitor world.
When I provide sound for my brother's jazz big band, I use snake #4 to mic the horn section.
Hope this helps a little.
