XML Sitemaps have been one of the main features in the Google Search Console for many years, however their true relevance is a debated topic in the SEO industry. They can be critical for the 1% of sites that are inaccessible to crawlers on their main pages, but they’re usually of little to no value on sites that are easily crawled naturally.
That applies to basic XML Sitemaps, which are simply lists of URLs, often with a date of last update; but the vast majority of people using a date of last update are auto-generating them incorrectly so are giving false information to Google, thus they’d be better off not using XML Sitemaps unless their URLs are simply not getting crawled without them. Google knows this so takes XML Sitemaps data with a huge pinch of salt.
There are plenty of advanced features for conveying extra metadata that are sometimes worthwhile using though, if you have complex content formats for example.
