A few caveats.
These are CEFs, not ETFs. You may or may not be able to sell your shares when you want to.

They are leveraged. More upside, more downside.

I could not find the expense ratio information on the Nuveen website. I suspect they are 1 to 2%.

The 7% yield almost certainly includes a return of capital component. I can give you a 10% yield for 10 years without any effort by just taking $100 from you and paying you $10 per year.

Credit quality is mostly junk - at least some of the bonds are going to default.
