If you're shooting raw, don't rely on the camera's highlight clipping warning. You could be throwing out some very recoverable images.
A HUGE benefit of shooting and processing Raw files is that they contain a lot of data that gets thrown away by the jpeg conversion, including highlight and shadow "detail" that the in-camera preview can show as "clipped" because that's what would happen if you got the out-of-camera jpeg. In fact, viewers that "show" Raw files but don't actually process them typically show you the "embedded" jpeg that the camera embeds into the Raw file, and so you are looking at a jpeg and so you might delete a shot that otherwise could be recovered in highlights and shadows. Here we aren't referring typically to "bad" exposures, but more fundamentally to scenes of a high contrast that with "normal" settings (such as using the Standard Picture Style or especially the Landscape Picture Style) the jpeg produced would show that clipping.
But the good news is that Raw processors can recover a lot of those scenes! In fact, you mention Lightroom, and Lightroom has a very powerful set of Highlight and Shadow tools. Take a bright sunny day but with a bunch of clouds, and the jpeg will typically blow out a whole lot of those clouds, but with Lightroom you can dial back the Highlights tool and Wow, a whole lot of cloud detail comes out! The same goes for darker "shady" areas that a jpeg would pretty much show as (clipped) black, a good Shadow recovery tool (such as you have in Lightroom) can make a huge difference!
Now sure, you can mess up and image by significantly overexposing or underexposing, but to me Lightroom lets me scroll through my images and if one is too bad, I just mark it as a Reject, and then at some point I can Filter to show only Rejects, and Delete them, a pretty quick process!
