For what ? Patch cable or inside wiring ?

Not important. Short lengths, small currents.

"Nude" copper slowly oxidises and becomes difficult to solder
after some years. Flux and/or fine sand paper help.

For patch cables, you want to get as many colours as you can.
Gotham sell cable by the metre (DGS-1 and GAC-1 in four colours
and GAC-2 in eight colours).

Single-stranded wire is for installation. OK for inside wiring,
bad idea for patch cables.
