Any you listed could work; my preference would be to mount the rod on the window frame:

I don’t like ceiling mounted rods, some seem too awkward looking and some seem too hospital room divider.

I reserve the right to change my mind if someone shows a great type I’m not familiar with. :D

Thanks Jilly! That looks great. What would I search for to find those rods/track?

Or is that just a generic curtain rod? Hard to tell from the photo

Emily, any normal rods would work, they’ll just need to have flat finials or no finials on each end.

Or you might be able to use a French return rod. This would be my preference, especially for black-out function. No light coming in on the sides.

My mock-up is just a line I drew. :D
