Perhaps a floating colony like those proposed for Venus? There might be a Goldilocks zone in the atmosphere. If not then there may still be a comfortable location in near orbit where the heat would be tolerable. It’s interesting to think of ways to overcome an extreme gravity environment though, perhaps suspension in a liquid would counteract some of the effects?

How would you float something in a hydrogen atmosphere?

Not float, but you can keep aloft while spending minimal energy using https://en.wikipedia.org/wiki/Dynamic_soaring

Jupiter seems to have sufficiently dynamic atmosphere. Not sure about cold brown dwarfs...

> Some of these weird worlds are even relatively close to Earth's temperature and could be cool enough to have water clouds in their atmospheres, according to the statement.

Hot hydrogen would.
