What is the best way to make the language (locale) and currency selection interface, together or separately?

Question

User interface

1) The user selects a language (locale) from one list and separately selects a currency from another list.
Plus: the user can see prices in any currency.
Minus: two actions are required from the user.
Example - booking site
2) The user selects only one country-language from one list, and the currency is set based on the country.
For some countries where more than one language is spoken, there may be more country-language pairs, respectively.
Plus: only one action from the user is required.
Cons: The user can't see prices in different currencies in the same language.
Example - microsoft site. I'm
more inclined towards the second option, but I want to understand all its disadvantages.
Which option do you choose and why?
And on the etsy website, everyone chooses separately: country, language and currency. Why did they do that - I do not understand

Answer 1

It is better, of course, to choose only the language, and let him choose the currency according to the user's location. For example, the iHerb website. Although, this site selects both the language and the currency by location.

Answer 2

It's funny that no one has yet thought of combining them into one droplist, which, when activated, shows two lists (with countries and currencies). You press, you choose from two lists, and if the page needs to be reloaded to apply the settings, you also press some OK button

Answer 3

As for me, it’s better to do it separately, the same aliexpress cannot be used in Russian, but I would like to see the prices in an understandable currency. And about auto-detection, it's annoying when you go to the site through some kind of vpn, the site determines some kind of Farsi and try to find the language switch there
