Get access to all prices in storefront

Hello, please tell me whether it is possible to override the output prices throughout the storefront? (need to add additional text after each price in the storefront). Is it possible to override the currency ( {{ products.calculated Price.unit Price / currency}} ), or is there some other way?

In order to override prices in the listing and detail pages, you can use ProductEvents::PRODUCT_SEARCH_RESULT_LOADED_EVENT event and for overriding prices in the cart you can use cart processor.
