Not terribly hard to cover in instanced combat since the tank will usually cover me.

Why do I want to use Corps-a-corps? To get in, quickly unleash a melee combo, and get back out. Biggest obstacles? Enemies trying to hit me while I'm close, especially with attacks that interrupt the combo. Solution? Don't let them hit me -- CC lockdown.
So you got Stun, Blind, and Pacification, and I dunno which ones are least-resisted, but I can tell outright that Stun is the most applicable to an ideal lockdown maneuver.
Though, you seem to be looking at things from a "Solo Red Mage vs the World" scenario.

When in reality, the majority of Duty Fantasy XIV is in Duties. Which means you have a Tank (Hopefully) holding aggro. Thus making CC effects on CaC/Displacement redundant (Much like every other CC effect that DPS jobs have. Outside niche situations where things like Leg Sweep/Head Graze/Arm Graze can interrupt an ability - Which is rare in of itself, but also rare to actually have a DPS put these things onto their action bar)

Like, the biggest obstacle with Displacement, isn't "Enemies chasing after you" it's Duty arenas being so small that using it will yeet you off the edge to your death.

Similarly, using CaC, the biggest obstacle isn't "Enemies trying to hit you and need locking down" it's the fact that you're a squishy mage and thus don't have the natural tankiness to deal with mDPS related mechanics (That and well... Most attacks in melee range would simply be the telegraphed ones that you simple walk out of... Annoying when you just wasted your mobility skill but not the biggest deal)

Any "CC" effects would only be notable in solo Overworld/Eureka content or would be minor ways to aid a Tank - Of which, Stun has the highest chance to actually make things worse for a Tank due to Diminishing Returns.

So... Speaking of which... CaC would make the most sense if it gave you a small shield. Not as strong as BLM's Manaward (Especially since Manafication gives CDR on CaC) but a little something so if you do get cleaved, you don't hug the floor. Which would also still be useful for soloing.

Displacement is the skill that has more flexibility, because it has that issue of arenas being too small for its use so it can more easily get away with having niche status effects on it. (Alternatively... Scrap the skill entirely and just make it so Corps-a-Corps has a ~5 second window to reuse the skill and let you backflip to where you originally cast it from, thus bypassing the static distance it moves you being harmful in small arenas and giving RDM an additional button to replace with a new skill instead)

As far as those 3 status effects go...

Blind tends to be resisted the least. Pacification gets resisted by many bosses as well as get put on DR by Paladins using Shield Swipe. While Stuns get resisted the most and are more easily put onto DR (Especially with Monks because Riddle of Wind is literally 2/3 stuns to put the 1 minute of immunity into effect...)
