There's a number of moves that don't particulary care about being cc'd:
- Magnet, due to its double-hit nature, will usually lead into a techchase against cc-attempts or ignore them entirely if the knockback is high enough. There's also the option to hold magnet a bit before releasing to to rack up a bit of extra percents against cc'ing opponents, which gives them only a few frames to counterattack, but on the other hand gives them a chance to do so. The one thing you have to do to avoid magnet being cc'd is hit with a holding hitbox right before the release hitbox.
- DAir as a meteor similarily can't be properly cc'd and will usually knockdown the opponent instead until high percentages. If the opponent isn't knocked into the air from DAir's hits (i.e. what you usually use the early hits for), cc'ing even does nothing at all, so you can followup with whatever you'd have anyway.
- Grab of course doesn't care about opponents holding down. As always you shouldn't use it to the point of being predictable, but keep the option in mind as it's the surest way to get a cc'ing opponent off the ground until high percentages.
- Theoretically footstools also ignore cc'ing and prevent it for the followup (ASDI down's still possible). Unless the opponent is mixing up between shields and cc's you'll usually be better of with DAirs, though.
Another important option against cc'ing are simply well spaced attacks. Depending on the opposing character, your spacing etc., punishing e.g. a well-spaced DJC FAir out of a cc can be very hard to impossible. You may only get a few percents out of the exchange, but if you're staying safe during it, that's a win as well.
PKF against cc'ing opponent is kind of a double edged sword. You get the percentages out of it, put you won't get enough frame advantage for any guaranteed followups unless you're auto canceling PKF and acting immediately after it. It can put opponents into an awkward position if they weren't prepared for it, but your PKF getting cc'd can also get you punished for trying to followup without expecting the cc. E.g. it's easy to escape any grab attempts from Lucas by buffering a roll out of the cc (using shield+c-stick) and then punish the grab.
So, in conclusion: Space your attacks well, know what your options will do against ccing opponents and be prepared for those situations. If you know your opponent will be trying to cc you can go for either a grab or a (possibly DJC) DAir depending on what gets the better followups/is less likely to be punished.
