Wizards isn't going to do it for you, because frankly, what you're asking for is stepping on blue's toes (and blue doesn't even get that many great cantrips anyway, often there's years between two playable blue 1 mv cantrips). That means you've got to take matters into your own hands if you really want those great, cheap black cantrips. All I'm saying is, use custom cards, they're great!
I feel called out
I didn't advocate giving every color preordain. I'm perfectly okay with narrowing the types of cantrips blue gets as a consequence of giving some of them to black.

That's not entirely accurate. While all your examples are valid ways for red to "draw" cards, WotC is also perfectly fine with printing stuff like Thrill of Possibility, for example, which gives a player way more agency than the cards you mention. The problem with Flooting is that it ticks too many boxes; it is aggressively costed, it has flashback (at a very affordable cost as well), and it gives the player the maximum amount of agency by drawing before discarding. Flooting's rate is simply too high. Note that Careful Study is a card that never caused any problems, even though it does exactly the same thing at the same mv. The only difference is that CS doesn't have flashback, that's what put Flooting over the top. I also don't think we are ever going to see many mono red cards in the future that draw before they discard. That's been firmly established as blue's way of looting in the past few years.
What isn't? Thrill of Possibility is the same category of card as Catharthic Reunion, which was my arbitrary rummaging stand-in. And the conversation was about the color pie, so while yes, red also doesn't get literally Faithless Looting also for power level reasons, my comment was about its mechanics, which you echo. Red doesn't get to loot.
