Unpopular opinion: there are bad examples, just like with any design trend, but the basic layout scheme for most websites for desktop use peaked with the "thin top bar & nav, 2-3 columns, left of which may also be navigation" standard style of the mid to late '00s.

Other designs are more convenient if you want a very easy-to-write responsive layout, and some sites do actually need something different, but that was as good as we've seen, in general, for desktop. You can't do it now because it "looks old" and people will assume your site is defunct, but it's the best.
