Is a TDF a good choice for growing my money, in this case? I plan to use it for a house down payment and withdraw it in 5-7 years. I’ve been thinking of putting it in a 2030 or 2035 TDF. Should I go this route or just VTSAX and chill?

Background: USA, I will be saving in a taxable account, and I want to minimize my tax liability as much as possible.
