Answer 1

Use $this->addChild function to add child block. Ex:

    $this->addChild(
        'back_button',
        'Magento\Backend\Block\Widget\Button',
        ['label' => __('Back'), 'template' => 'Vendor_Moduel::template.phtml' 'class' => 'cancel']
    );

Then in parent block template use $this->getChildHtml('back_button'); to render child block with template.

PS. Better to use layout to define blocks and templates

In your block file,

protected function _construct()
    {
        parent::_construct();
        $this->setTemplate('Magento_Config::page/system/config/robots/reset.phtml');
    }

check for _construct() method not confused with __construct().

You can set your Namespace_ModuleName :: path/to/template.phtml
