This is my first Hinoki, it'd about 50 years old. I need some recommendations on a new pot for it, as you can see the present pot is butt ugly
any advice on this tree would be appreciated also. Pruning, thinning and styling advice.

Nice. I love these. My very first bonsai I made a long time ago looked a lot like this. Brings back some memories.
If it were mine I would look around for just a plain unglazed oval pot for it.
I would just pinch the new growth this year and study the tree to formulate a plan to see what changes if any I would do. You have time.
This is a very nice tree. Although it may appear that the tree can be left as is for now, that is actually not the case. First, a good time to do major pruning and styling on these trees is late spring, early summer. That being said. This tree has already begun to out grow it's trunk. Meaning the silhouette is too large for the trunk. If you let this go, this tree will be out of hand within a year. The longer you wait, the more the current design might become compromised. If it were my tree I would first assess the entire silhouette. Study the ends of all branches, not only sides, but everywhere. Then, pick the area on each main branch where you can cut back. At that point, you will need to wire the designated new end branch into position. Also, while you are at it, you can remove any growth that is growing underneath branches. Also, always leave light, new green foliage. Never pinch or cut back to wood or even old green. Even piching back to old green, the tree may never grow from that area.
Honestly, the above steps are quite time consuming. You will probably need to put aside a good 10 hours to complete the work. This includes assessing where to cut back all the branches and then wiring the new ends in place. Actually, you might find that the entire tree needs wiring, specifically a ton of fine wiring. In which case, you might be talking about a couple of days of full work. I have trained my hinoki for 12 years. So I figured I would help you prevent some very preventable issues with this tree.
Here is a virt of a nice start for the silhouette.
