I believe you can RBF (resend the utxo with a higher fee) to a different address: your own. That is in effect cancelling it. You just pay more fees to do it of course.
Transactions that aren't confirmed (in a mined block) aren't considered spent, but while they are pending and chilling in the nodes' mempool, nodes will not accept another transaction for that same UTXO unless:
the old one expires due to very low fee and everytually getting purged out the mempool by most nodes, or
it's a valid RBF transaction for that same UTXO
I can't check different wallets right now, but from memory, RBF in most wallet apps is presented as a way to speed up a transaction and they may not allow inputting a different address in the UI to keep it intuitive and simple. But it is technically possible to do an RBF transaction with different output address.
BE AWARE! DO NOT DO RBF ON A OPENING/CLOSING LN CHANNEL TX ! That will end up in zombie channel and you will have to use chantools and is complicated if the peer is not cooperative.

Better use CPFP as it nicely explained here:

On Coinbase there is undo before confirmation zero is established but you have small time to undo.
you cannot replace with a lower fee, must be at least 1 sat bump. a tx will be purged from mempool eventually if it pays below Minimum Fee.
