“I read a book about ETFs, but didn't really understand why I would want those over ordinary MFs.”

ETFs are more tax efficient. Most never distribute a capital gain. Mutual Funds, especially active ones, can distribute very surprising cap gains, even in a losing year. I found this out the hard way :-(

ETFs trade throughout the day, so you know your entry and exit price.
