What plugin do you use for multilingual in wordpress?

Question

WordPress

Google gave up to 10 pieces .... I tried polylang, fumbled for an hour with the settings and read the doc - it didn’t start, then it only opens the English version, then the English menu doesn’t show at all ...
What plugin do you use? (except for paid ones)
And another question is whether there is such a simple plug-in that could only, depending on the language settings in the browser, translate the user to the appropriate address? On one of the sites, I have a copy of the site installed in the EN subfolder and translated into English, thus multilingualism is implemented.
