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.
