Well, I can cover a few of the easier ones.

For CFOP, any F2L case where both pieces are in the U layer, as well as any case where one piece is in the correct slot (with any orientation) and the other is in the U layer, can be solved in 8 or less HTM. Cases where pieces are in slots can take more than that.

OLL: 6-11 moves
PLL: 9-14 moves
LL: 6-16 moves

Roux L6E Orientation: I believe that the worst case (6 flip) is 11 STM when solved with M U. I haven't seen it tried with UDRLFB, but I'm inclined to doubt there's anything more efficient with HTM, as all of the 4flip OLLs are 11 HTM optimally, and that's without the constraint of having to keep the corners solved.

I think that any L4E Roux case can be solved in 4 STM. Not sure about that one, but can't think of anything that would be an exception.

Things like 1x2x3 blocks and 2x2x2/2x2x3 are waaaay harder.

I think studies on optimal cross solutions have been done, but I don't know where to look for one. If you want an decent upper bound estimate, find a brute force solver and look for cross solutions for superflip.

I use Rw' F R U M' U' R' F' R. Is that 10 HTM?
 
I just had a 21 minute feet DNF

Was up to T-perm at about 6:30, took 1:30 to do it, had a corner twist. Tried to twist it back, ended up twisting another corner in the wrong direction. Eventually twisted it into a solvable state. Did OLL, had an A perm. Popped.

Feet is the worst.
 
applying CPF2L without preorienting edges will result with an LL subset solvable with <R,U,M,r>
how many cases are there? 600ish?
some algs:
U R2 r' U R' U R U' R' U r U2 r' U' M'
r U r' U R U' R' M' U' r' U2 r' U2 R U R' U r
U R' U2 R U R' U' R U R' U R U2 r' U' r U' R' U M U r
limiting it to those moves might make alg recall terrible though, just like 2GLL for me :/

Well technically they're just <R,r,U>

I'm not a math guy, so I can't help you, but I do particularly love this subset because of siamese cubes. It's like doing OLLCP every time. Ha.

Become a master of Rubik's Cube™ in under 4 days - for only $4 (original price $49)! You will be lectured by a certified Rubik's Cube™ Professional, who has the ability to solve Rubik's Cube™ in less than 2 minutes! That's a World Record!

The good news that he will not be using notes! Yes, that's right. He did not learn with it, so he will not teach it. Instead, he will show you the moves with arrows and shapes. As the title says, you will learn to solve the cube in 4 days, but that does not mean you will be FAST in a week! NO, it will take you some time depends on how much you practice, to solve the cube in 3 minutes or less, and you will learn in a way that will enable you to memorize all the steps in 4 to 7 day.

Thank you.

Hilarious! Wait, is that really >1000 people signed up?

Oh and there's another one where 8 people signed up to learn to do it in 3 minutes for $97. See all 10 steps in HD slow motion, and become the life and soul of every party! (Where are these parties? I want to go.)

I have a better idea - for only $50 I will teach you to use Google. In only 2 days, without notes!

:D
 
And once again I find myself in the situation where I'm tempted to switch to ZZ. I used it once for a month or 2 and went back to cfop again. It's not about times, I know that it won't magically make me faster, at first it'll make me much slower. But I just love ZZF2L, the fixed orientation(if you choose just one) and therefor always knowing exactly what belongs where. Having edges oriented makes for great use of COLL and in the future possibly ZBLL. But now it's even more frustrating because I'm starting to hit sub15 again.
Last time I switched I was still struggling to get sub 20 I think. What made me go back was just frustration with EOline and being impatient because I got slower and didn't improve fast. Also the freedom in ZZF2L and having 3 pieces to track was really hard compared to cfop F2L.
I don't know what to do :/ any recommendations?

If you like ZZ more, then switch, even if it means your times will increase. For me enjoying the solving provided by the method is more important than seconds or miliseconds.

Thanks! I think I'm just gonna practice it. My EOLine planing is already much better than it was when I first switched. I guess because of cross planing experience. I did a couple of solves and man, is it fun finding tricks to build blocks. It's a little challenge to get rid of CFOP F2L thinking and taking adventage of more freedom in moves, but it's great fun. I'll stick with it for now, and see how well I get used to it. Not gonna time myself anytime soon though.
