I prefer my cascades to have a single cascading branch so my first step would be to pick whichever one of those has the most potential. I also like a short apex on mine so I would train a leader out of either part of the other branch or one that follows the base trunkline whichever gives me the best movement and potential. Then develop foilage pads. The movement of a cascade should always be dynamic both horizontally and vertically. Like a multistage waterfall (branch) that drops from pool (foliage) to pool. Hope this helps. Look at as many pictures as you can and see what the tree does that works for you. The juniper you have looks like a good candidate but you can see it alot better in person than we can from a single distant pic. It's up to you to make the major decisions and you'll feel better about the tree if you do.
I would start by drawing a vision for my design. For a traditional cascade, you want the apex centered over the pot, and the point of the descending branch centered under the pot. How you get there is the design
Start with this, and then let's discuss. Always have your final vision in mind BEFORE you start worrying about which branch to bend where.
A light trimming wouldn't hurt now -- pinch the tips back, all over the tree. That would send more resources into the roots as they recover.
Be careful, tho, not to rock the tree in its pot as you pinch. That can break fine roots. I think this would be an occasion for scissors, even tho the cut tips would brown. (Unsightly but not harmful.)
As for your posting difficulty, sorry; I have no idea.
Most of the best cascades I have seen in person as well as photos have trunks that leave the soil at an angle. You don't need to change the angle now, but keep it in mind when you decide on branch selection and placement.
