Yes. I was given 3 options (I believe) during installation. I chose the second one. [Standard]. Are there fake ones?
Fake or official, it depends on where you download Electrum wallet software for installation. Fake wallets have similar UI like official wallets that help them to scam.
Verify your wallet before using.
Still can't find the RBF from Tools. Sorry I can't post too quickly.
It's not too difficult and you will see using RBF easier next times.
