Beginner crypto investor looking for platform advice

Hello,

I'm planning on putting $1000-1400 into Ethereum and $600-800 into Bitcoin This is my first time investing (and crypto), and I was planning on using Coinbase Pro because of smaller amounts of fees. I also read somewhere that some people would buy crypto on Coinbase then transfer to Coinbase Pro for trading, but would that work with the amount of money I plan on investing? Or, would it make more sense just to deposit that cash into Coinbase Pro and invest from there?

Sorry for the beginner question, thank you!
