Trade-centered run?

I am new to EU5, but I have hundreds of hours in Victoria 3.

I want to have a trade-centered run in EU5.

I want to use both land and sea for that.

I want to do a lot of manual meaningful profitable trades. I want to manipulate trades, like increasing a demand for some goods in my markets artificially and then kind of monopolizing their exports, etc.

Also to do something fun with manipulating markets.

I am mostly interested in trade, but I want to mess with minting, taxes, loans, etc.

What country should I choose and what could be my goals for the game?
