I have requirement that for X product. Payment will be Authorized & Capture later. For other products it should be captured immediately.

So when user checkout with Paypal then i have to do this changes.

magento\vendor\magento\module-paypal\Model\Api\AbstractApi.php

public function getPaymentAction()
{
    return $this->_getDataOrConfig('payment_action');
}

My only concern is which function should I override on basis of my condition?

For paypal express Magento/Paypal/Model/Api/Nvp.php class is responsible for process request and response.

Magento first call callSetExpressCheckout, it return token and this token is use for next nvp process.

Then check following:

Now go with following class Magento/Sales/Model/Order/Payment.php

/**
 * Authorize or authorize and capture payment on gateway, if applicable
 * This method is supposed to be called only when order is placed
 *
 * @return $this
 * @SuppressWarnings(PHPMD.NPathComplexity)
 * @SuppressWarnings(PHPMD.CyclomaticComplexity)
 */
public function place()
{
.....
}

Check following line

$action = $methodInstance->getConfigPaymentAction();
