Again, I am not just in disagreement, I actually hold the complete opposite opinion. Int score is more important in 5e than previous editions in my view. As I reviewed the spells, I increasingly realized that Int had become more important than to wizards of previous editions.
It took me a fair while but now I think we might not be so completely opposed
If my argument was "wizards use their Int less often now" your reply and opinion makes perfect sense.
But I'm not. Sure more spells than ever require a check involving Int.
But my point is that nailing those spells is easier than ever (at higher levels). Once you have a "decent" save DC you should probably not reflexively strive to improve it further, at least not without considering your alternatives.
So Int is important in the sense you can't get by without it, but it's not important in the sense you absolutely must have the highest score to be a well-functioning wizard.
At low levels a DC of 13 gives you the impression this will be a hard slog, since DC 13 means almost every monster stands a decent chance of saving, and your prospect of having a "save at end of each round" spell stick around is bleak.
But at high levels a DC of 18 or 19 is massively effective. Why, because the saves of the monsters haven't improved, like at all.
Assuming clever play, that is. You still need to target a weak save.
A monster with a +1 bonus will find escaping from a DC 19 spell almost hopeless. Magic resistance barely helps at all.
At this time, the wizard could well be much more helped by looking at a Dex, Con or Wis increase than to find a way to increase her DC further to 20.
So I'm not really arguing against what you say. Sure a numeric overview of the wizards attack vectors indicate Intelligence is involved in most of them.
And for the spell attack part you're completely correct. If your build relies on cantrips, there's no downside to a higher Int.
But I'm sure you of all people would agree that if you want to simply blast people, you should play a Sorcerer or Warlock or ranged Fighter, eh, Mr God Wizard?
