I've used graphical tools very similar to this, and I always come back to this:

   du -h | sort -rh | less

(might have to sudo that du depending on current folder. on macos, use gsort)

You just immediately see exactly what you need to delete, and you can so quickly scan the list. I'm not a terminal die-hard "use it for everything" kinda guy, I like GUIs for lots of stuff. But when it comes to "what's taking up all my space?" this is honestly the best solution I've found.
