How to build custom theme with page and static blocks in Magento2?

Question

I am trying to create custom theme with inbuilt Cms pages and Blocks? For example once the theme files moved and installed can able to see all the blocks and pages are created in magento.

I followed below link https://www.cloudways.com/blog/create-custom-theme-magento-2-part-1/

Which is for overriding luma theme but not able to Preview the theme with content.

How can we create theme with full package along with slider, Blocks and widgets like the Paid themes? For example in this Url: https://www.hiddentechies.com/bizkick-responsive-theme-magento-2.html

Once we buy we will get full package with all pages,blocks and widgets. How we can create like this exactly from scratch? Please anyone suggest with links or with step by step Guide,

All i need is i am going to create two custom themes, so page,and blocks are different for each theme.

So whenever a,theme is applied in admin, those page content should show in frontend.. Thanks

This is too broad question but i tried sum up for you. You can create the basic theme with currently provided link. But for creating theme data import you need to create module's for importing data. Like if follow this example for creating the cms block for run time.

Create installer Script

Create csv data

Save with model

Now taking example

<?php

namespace QaisarSatti\HelloWorld\Setup;

use Magento\Framework\Setup\InstallSchemaInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\SchemaSetupInterface;
use Magento\Framework\DB\Ddl\Table;

class InstallSchema implements InstallSchemaInterface {
    private $blockFactory;

    public function __construct(
\Magento\Cms\Model\BlockFactory $blockFactory
 )
    {

    $this->blockFactory = $blockFactory;
    }  
    public function install( SchemaSetupInterface $setup, ModuleContextInterface $context ) {
        $installer = $setup;

        $installer->startSetup();

       $testBlock = [
         'title' => 'Test block title',
         'identifier' => 'test-block',
         'stores' => [0],
         'is_active' => 1,
         ];
        $this->blockFactory->create()->setData($testBlock)->save();

        $installer->endSetup();
    }
}
