The mode argument can be SemanticZone which causes the selection to take the surrounding semantic zone.

In this example, the triple-left-click mouse action is set to automatically select the entire command output when clicking on any character withing that region:

local wezterm = require 'wezterm'

return {
  mouse_bindings = {
    { event={Down={streak=3, button="Left"}},
      action=wezterm.action.SelectTextAtMouseCursor("SemanticZone"),
      mods="NONE"
    },
  },
}

See Shell Integration docs for more details on how to set up your shell to define semantic zones.

The mode argument can also be "Block" to enable a rectangular block selection.
