Maybe you can refresh my memory, but I don’t recall ever watching a video where someone actually narrates on camera. They are a host. So if you are doing a production that requires someone to take the viewer and show them around or something (like Mike Rowe in Dirty Jobs) then hire a host.
To me, documentaries typically hire narrators. I guess it’s your call though, depends on what style you want to embrace. I don’t know whether or not there is a right time or not for narration/host. You just have to feel it out and decide whether it works or not. I’ve seen documentaries with hosts and I’ve seendemonstrationand other related videos use real narrators.
