a checkbox field cannot be checked by default?

also: Admin Action "Field Set or Search and Replace" cannot batch set a checkbox field's value?

Yes it can, but not via the field settings in the GUI. You can put this hook code in site/templates/admin.php above the require($config->paths->core . "admin.php"); line:

// sets field checkbox to checked on new pages with template basic-page
$wire->addHookAfter('Pages::saveReady', function (HookEvent $event) {
    /** @var Page $page */
    $page = $event->arguments(0);
    if ($page->isNew() && $page->template->name == 'basic-page') {
        $page->checkbox = 1;
    }
});

You just need to adjust template and field name.

Everytime a new page with that template is created the checkbox will be checked by default.

If you have TracyDebugger installed, you can do this with a one-liner in the Tracy console in the backend:

$pages->find('template=basic-page, include=all')->each(function($p) { $p->setAndSave('checkbox', 1); });

I need to just set it once for an array of pages because the checkbox field would be new to them. After that the checkbox field would be set upon page creation.

I'll give the Tracy Debugger option a try then.

Thanks @gebeer!

just curious, how is a InputfieldCheckbox field different to a FieldtypeOptions field with only one option?

FieldTypeOptions gives you different UI and stores data in a different way. If you just need a checkbox, I'd go with InputfieldCheckbox. Less overhead.

Another option is to use the Toggle InputField: https://processwire.com/blog/posts/pw-3.0.139/#new-toggle-field as it has a "Default selected option" (yes / no / no selection) setting among other useful settings.
