First, I am not sure how to tell if either wallet has or had RBF enabled.
The latest Trezor upgrade support RBF, so I do not know which one you are using. For ease, copy and past your txid/transaction hash into the search space you will see on blockchair.com. You will be able to know if the transaction support RBF or not.
Second, it doesn't seem like either wallet allows me to utilize CPFP ..but then again I am no-techy and honestly completely lost at this point.
1. If the transaction has a change address UTXO, you can track that on blockchair.con also, then you only need to send fund on your wallet including the change address UTXO into a new address on your same wallet, in this case, you will have to increase the fee in a way it will be enough to get two transactions confirmed at ones.
2. The receiver, if able to spend unconfirmed transaction, he can just send the unconfirmed transaction to another address on his same wallet using high fee that can get two trasactions confirmed in time.
I was watching an Andreas video about stuck transactions and he stated that regardless, in 14 days it will be settled whether included in a block or cancelled...is this accurate ?
Know that we do not have a central mempool, on the 14 days, it is normal for the trasaction to leave the mempool, but the way all mempools are working can be different, for Bitcoin core standard, it is 14 days, but I do not know about another full node wallet, there can be cases a transaction that thought to have being dropped from mempool still gotten confirmed after 14 days, which means the transaction only just dropped from most mempool, not all. That is why the use of coin control is very important in this case, so that the transaction can be rebrocasted using the same address he was last sent.
