I want to set the color of Cetz objects (such as line, circle, content, ...) to red.

The problem is that they aren't an element. I wonder if they share a common element so that a show rule be applied to it can affect all of them.

Dou don't use #show here, but rather the cetz function set-style:

#cetz.canvas({
  import cetz.draw: *

  set-style(
    fill: red,
    stroke: red
  )

  line((0,0), (5,0))
  circle((), radius:1)
})

Is there a cetz alternative to show, for example in order to draw a specific shape on the coordinates of every cetz.content?

No, you could create your own function in the canvas scope to do that though:

let show-content(pt, ..args) = {
  content(pt, ..args)
  circle(())
}
