Thanks! This answered everything.
I'm curious if the bumped fee that the GUI suggests is changeable?
Increased the fee from 200 to around 3800 sats. I assume this is based on the suggested fee, but what if I would like to increase it higher than this, without increasing in steps?

I don't see an option to specify the fee rate in the GUI, but you can use the console (or bitcoin-cli) for that. For example, to increase fee rate to 15 sat/vB, you would use `bumpfee "your txid here" '{"fee_rate":15}'`.

<p>I have no knowledge about Bitcoin Core and attempted my first transaction, which failed due to low fee due to a basic math error. (Did not notice it was per kilobyte rather than per byte.)
It is currently stuck on chain, in its unconfirmed position.
I see that I likely had the &quot;Replace-by-fee&quot; option enabled.</p>
<p>How does one trigger an RBF?
I have attempted searching around but could not find a definite &quot;guide&quot; on how to perform this in Bitcoin Core. To my understanding I simply send a new transaction with a higher fee to the same recipient and it should replace the old one?</p>
<p>Also, when sending this small transaction (~36k sat), I viewed the txid on explorer and saw that my entire balance was sent, with the remaining BTC being sent to a different address.
What is the function behind this?</p>
<p>Hopefully someone could explain this to me in a newbie friendly manner?</p>

If you're using the GUI, head over to the "Transactions" tab, right-click the pending transaction and choose "Increase transaction fee". If you're using bitcoin-cli, use the `bumpfee` command.

The second address you're observing is your change address. See for example [this](https://bitcoin.stackexchange.com/q/9007/121614) or [this](https://bitcoin.stackexchange.com/q/736/121614) question for an explanation.
