D&D is deep and has 2 layers to increase it : flat bonuses (very limited, mostly bless or equipment) and the advantage/disadvantage mechanics (many possibilities).
Increase the variety of the "flat bonus layer" would add more depth to the game and it would increase our possibilities/the meaningfullness of our decisions (not sure "meaningfullness" is a real EN word..)
Interesting thoughts. If there was an Enemy AC (& ST) slider, then it might be more useful to have flat bonuses instead of Advantage at very high enemy ACs

That's the only reasons why I wrote "if you can jump further than you can move". I may be wrong.

Another related question : Should we be limited to 1 jump / turn ? If it only cost movement, could I jump 3 * 3m if my speed is 9m ?
To your first point, I think technically (and according to Jeremy Crawford) it's not allowed. But I think that's a bit dumb. If your jump distance is greater than your movement speed of 30 ft, it makes perfect sense that you can jump more than 30 ft.

To your second point, there should probably be a 1 jump/turn limit? If only to make things simpler and less mario-like. Even in rare cases where jumping 3x would be preferable, I think the tedious-ness introduced by doing so outweighs the positive benefit.

I vote that they shouldn't be simultaneously allowed options. "Backstab Advantage" will be the most lenient form of flanking
This would probably require 2 toggles (Backstab / Adjacent Ally / Flanking) and (Advantage / +5 / +4 / ... / +0) but that's fine.
