There is nothing, and I mean nothing, that doesn't benefit from these 5. You can always add other spices, too, but these are the baseline for every single dish that isn't meant to be sweet. And even on some sweet stuff, it's pretty good. I tried it on waffles once and it was amazing.
I agree with the first two and sometimes the last (though I tend to go for stocks instead to get the umami). I'm really not a fan of the onion and garlic powder, though. If I need onion and garlic I get onion and garlic. Don't like the powder forms.
