It may be because of how I use a computer, but I only use Spotlight as an application launcher. Because it's there I will type stuff in the "Search" box in Finder, expecting to filter on the filename of the current folder--instead it it searches "This Mac" and my results are variable names from open source code I've downloaded. Since it also omits results from System files and preferences, like ~/Library, I often use good old locate in a Terminal.
Windows Control Panel is an unholy mess. macOS' Preference Pane search, as well as searching for menu items under Help inside any app, is a godsend.
