is CPFP another way to refer to RBF or a totally different thing?

both refer to the same result: get a tx confirmed when is stuck with a low fee. But yes are a bit different.

one is literally replacing your transaction (Replace By Fee) and the other is simply incentivizing miners to mine both of your transactions since the new one ("the child") (with a high fee) depends on the previous one ("the parent")

👍 Also never do a CPFP when you have a stuck opening LN channel. You will end up in a bad situation to recover your funds.

Yes, I believe because the txid changes and you're paying into a multisig that the other party isn't necessarily aware about?

Also, with CPFP, you can accelerate transactions that you can't sign yourself unlike RBF. So if you're receiving an onchain tx, you can use CPFP to receive it faster by paying miners.

Exactly ! CPFP is nice when the sender do not have anymore funds to bump the fees, but the receiver is doing it from his side.

I did some tests in the past and I end up in that bad situation when by mistake I used CPFP instead of RBF for a channel bump. Is described in this guide
