Being a novice, this is all an untouched territory for me. I signed up for mempool.space, I learned how to see my transaction and its ETA. How do I find fees?
You don't need an account - just go to
https://mempool.space/ and look at the left side of the screen for the section on transaction fees, and pick an appropriate fee.
If you want to get a bit more complex, then try looking at
https://jochen-hoenicke.de/queue/#1,8h. This site shows you a graphical representation of the mempool, which each colored band representing transactions of a given fee. Knowing that each block will remove roughly 1 vMB of transactions from the top of the mempool, you can choose exactly where you want to place your transaction in the mempool and the appropriate fee rate to do so.
