Legato has the best chance.

Something like Gotham is to be avoided.

Thanks. I don't have that one. What do you think of Whitney?

Perhaps also FF Meta.

But I have not seen a good relative rating of how well they actually work for extended text.

I think Whitney is certainly better than Gotham, but it doesn't have Legato's secret ingredient – see my review here:

I like Verlag for text setting.

Thanks, I'll try them all out. I like verlag, too, I just think it can get uncomfortable if reading a huge chunk of it (I've also, personally, used it too much, I think.)
