Using a universally adopted format that could hold much more code would have been an immense advantage, I hope no one would argue against that. Higher read speed is just about the only argument in favor of cartridge at that time, but this read speed is wasted when the amount of stored info is much smaller and the need for said speed more or less goes away, so there is that.
Choosing cartridges, and mini-DVD for the Gamecube were ridiculous decisions that gained them nothing but potentially lost them a great deal.
