I urgently need a visual way to find which files and directories are taking up space on my Linux system. I used WizTree in the past, but I haven't found an equally convenient replacement. Running du manually is cumbersome and doesn't give me a useful visual overview. I tried QDirStat from Flathub, but it reports directories such as /var and /usr as only a few hundred megabytes even though they occupy closer to 20 GB, including when launched with administrator privileges. What disk-usage analyzer would you recommend?

If you’re okay with a terminal interface, dust or ncdu are useful. They let you browse directory sizes interactively instead of running a separate command for every folder.
Try Filelight or GNOME Disk Usage Analyzer (Baobab). Both provide a graphical, browsable view of directory sizes and make it easier to drill down to the files using the most space.
Disk Usage Analyzer, also known as Baobab, is a solid straightforward option for scanning folders and viewing their sizes graphically.
Duc is worth looking at. It indexes the filesystem first, then lets you browse the results through several interfaces, including a graphical and web-based frontend. The indexing step can also be scheduled if you want to monitor a server or NAS.
I don’t mind terminal-style interfaces, but I’d prefer something I can browse interactively with a clear layout rather than having to type a new command for each directory.
