The OP was talking about HandHeld exposures. You are talking about tripod exposures without mentioning your shutter speed.
What works for me obviously will not work for you. HH requires a shutter speed that helps prevent camera shake and for me, 1/60 second with a 35mm lens is about right at the end of a long day. But, I'll conceed, f/4 or smaller will also work at 1/60.
Exposure is exposure. There is no such thing as tripod or handheld exposure settings for fireworks. With fireworks (the actual burning part of the fireworks, not considering anything on the ground), it doesn't really matter what shutter speed you choose to use. Only the aperture setting will change the exposure of the burning fireworks.
If you use a shorter shutter speed like 1/60, you will get pretty much the same exposure for the image as with a much longer shutter speed (using the same aperture for both shutter speeds), but you won't see the whole burn of a shell like you would with the longer shutter speed.
f/4 at ISO 100 will guarantee overexposure of the fireworks. You will see an image, but the colors will be quite washed out as compared to setting the aperture at f/8 or f/11 (also at ISO 100, of course). Again, because of the nature of the subject, shutter speed is irrelevant for the exposure.
