You didn't answer the question. I suspect that once again you are making statements you cannot and have not substantiated. You don't know what you're talking about, IOW.
I don't know about Clorox...but I do know about oxalic acid and acetone because I've used both products for over forty years. Oxalic acid is is a wood bleach but it does not work for leather. Oxalic will bleach out iron stains that occur on vegetable tanned leather through careless handling. (a usage that goes back centuries) And the only reason it works is because vegetable tans are almost always wood bark based.
Oxalic acid has no effect on chrome tanned leathers. It has no effect on aniline dyes. It has no effect on water based dyes. It has no effect on finished leathers. It will actually darken (stain) vegetable tanned leathers.
Dye prep will not bleach the leather, either. It's purpose is to open the pores and cut through the greases so that dyes will strike evenly. Acetone will not bleach leather. It will remove finishes and pick ups some loose aniline dyestuffs but it is not a bleach.
Below is an experiment I did:
The first photo is of a series of swatches cut from different shoe leathers. Before.
From L. to R.:
1.Spanish calf, chrome tan, aniline dyed, struck through, little or no top coat. 2. Annonay French calf, aniline dye and top coat, not struck through. 3. Glazed buffalo calf, retan, aniline dye, struck through, top coat and acrylic wax. 4. St. Crispin burnishable baby calf (A.A. Crack), calf, veg tanned dyed crust, struck through, no top coat. 5. St. Crispin burnishable baby calf, veg tanned dyed crust, struck through, no top coat. 6. Burnishable buffalo calf, veg retan, aniline dyed (?), struck through, no top coat.
Second photo, veg calf, similar to, and a reasonable facsimile of, crust. Before
L.-R.:
1, aniline dye. 2. aniline dye. 3. Eco-flo water based dye. 4 Eco-flo water based dye. 5 iron stain.
Third and fourth photos, 48 hours after applying a liberal swath of Oxalic acid:
All the veg tanned leathers darkened some under the influence of the strong acidic wash. None were bleached. None of the dyes were affected. None of the finished leathers were affected.
The iron stain was removed.
It might be noted that oxalic acid can over-acidify a leather and destroy it. I once watched a colleague paint Oxalic on a perfectly beautiful pair of buttercup ostrich boot and within 24 hours the leather had darkened to a reddish tan and was dry to the touch. Despite conditioning they cracked and were turning to dust within three months.
Finally, yes, you can scrub any leather to the point where the colour will come off. But you can do that with pure water too, if you're industrious enough. That said, this is not only destructive to the leather, it is, bottom line, not a bleach.

Use all those solutions without washing/water isn't exactly going to get rid of the pigments? Its true that I might etched the top surface of the leather thus the decoloration and might as well use 600 grit + sandpaper. But who knows.
I will have a pair of suede boots made on my last. Calf suede is the go-to, but I'm also pondering about other animals that have similar hides. Naturally, I'm looking for the strongest suedes available. What recommendations do you all have?
If that's an honest question...then the honest answer is that someone who has not worked with leather extensively, or made shoes, or actually done the work (beyond dabbling)...tried, failed, succeeded, tried again, and again, and again,day after day, week after week, month after month, year after year, etc. ...is damn sure not going to know.
And while there is no onus, no culpability in ignorance, per se, there is a certain responsibility that comes with claiming / pretending to knowledge. Especially knowledge that one doesn't actually have. How many pairs of shoes have been ruined because someone...like you...gave un-informed and apocryphal advice with no objective basis to be doing so?
Too many people can't be bothered to take responsibility for what they say (or do) these days...don't even want to think about the implications.
Loose lips sink ships.

Kudu suede (reverse kudu) would be one option (I'm not talking about the fake alden 'Kudu', but the one that comes from culled antelopes).

I don't bleach shoes...I don't think it is good for the leather. That said, I do know the difference between "bleaching" and scrubbing / scraping the finish off. Which, given your admission above, you apparently do not.
And FWIW, I remove stains in leather with oxalic acid nearly every day. But, as I demonstrated in the above photo sequence,that's not bleaching either.
