From my understanding, seem that you want to custom price on your shop. We should see some useful methods for customizing price.

vendor/magento/module-directory/Model/Currency.php

 public function formatPrecision(
        $price,
        $precision,
        $options = [],
        $includeContainer = true,
        $addBrackets = false
    ) {
       ......
    }

vendor/magento/module-directory/Model/PriceCurrency.php

 public function format(
            $amount,
            $includeContainer = true,
            $precision = self::DEFAULT_PRECISION,
            $scope = null,
            $currency = null
        ) {
            ......
        }

 public function convertAndRound($amount, $scope = null, $currency = null, $precision = self::DEFAULT_PRECISION)
 {
        ......
 }

vendor/magento/framework/Locale/Format.php

 public function getPriceFormat($localeCode = null, $currencyCode = null)
 {
   ......
 }

For sample di.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Directory\Model\Currency">
        <plugin name="modify_around_precision" type="Vendor\YourModule\Model\Directory\Plugin\Precision" />
    </type>
    <type name="Magento\Directory\Model\PriceCurrency">
        <plugin name="modify_around_format" type="Vendor\YourModule\Model\Directory\Plugin\Format" />
        <plugin name="modify_around_round" type="Vendor\YourModule\Model\Directory\Plugin\PriceRound" />
    </type>
    <type name="Magento\Framework\Locale\Format">
        <plugin name="modify_around_price_format" type="Vendor\YourModule\Model\Locale\Plugin\ModifyPriceFormat" />
    </type>
</config>

If you're looking for the template that renders the final price of products, then bringing this (magento2/app/code/Magento/Catalog/view/base/templates/product/price/final_price.phtml) file to your theme should do the job.

And this file (magento2/app/code/Magento/Catalog/Model/Product/Type/Price.php) is probably where the final price is calculated.

Hope this helps.
