I like both your evergreen choices. I had a juniper in my courtyard against the fence called "Torulosa" which I loved. A little wilder than those other two, but you asked for other options. I considered both of the ones you're mentioning, I like those too. Google "Torulosa Juniper" and you will see lots of example photos. It's wider than skyrocket, but I pruned it, and I liked the fact that it was somewhat wider.

Edited to add that here is a picture of one of my four Torulosa junipers growing against my fence. I eventually took that one out to give the tree and the reddish shrub all the space, but that's how they look in a small space, sort of. Not really a good photo, but best I had.

Here's one above, from the other side, the one I kept. That's about their maximum size.

Here are two out of three, between a japanese maple that sadly died a short time later.
