Note that as of version 8.1 .UrlAbsolute() has been removed and I found one can now use .Url(mode: UrlMode.Absolute).

Url: content.Url, .GetUrl(...), .Url(), .UrlAbsolute() are all gone,

The proper way to get the Url is content.Url(string culture = null, UrlMode mode = UrlMode.Auto) which produces a relative-or-absolute Url depending on what's "best", but can be forced to produce absolute Urls with UrlMode.Absolute.
