If I need to know the details of a file (eg file extension, size, location, etc) I generally use the Finder for that, yes.
I do frequently convert file types through the Finder. Bulk converting a bunch of photos, for example, is easier to do through a file browser. Even if I were opening a different app to do that, a standard file browser would be the interface I would want for that.
It’s great if more iOS applications are storing files as regular files on the filesystem now. Apple should have encouraged that in the first place. There was some goofy notion they were going to get rid of the idea of “files” with iOS, but that’s not actually a good idea.
