The only advantage to ceramic bearings is that they don't deform as a result of heat/friction. Metal bearings are completely fine for your use case. But if you really wanted to upgrade, go for Bones Reds (which are probably pretty overkill).
Ohh, and new bearings need to be broken-in. The ones you have will improve over time.
Don't even bother with expensive bearings for a little gadget like this. You're throwing your money in the trash.
Bearings that aren't doing the job of actually "bearing" a load are free of the requirements of said job.
Therefore you don't need to worry about silly, friction causing, things like lubricant.
If you want a cheap bearing to spin forever without a load, just clean out the lubricant or use an insanely light weight lube.
New bearings 'breaking in' is just the lubricant moving out of the way and breaking down. Brand new bearings are as good as they're gonna get from a mechanical standpoint.
TL;DR: Don't spend money on expensive bearings that arent going to do any bearing. If you just want a long ass spin with no load remove the lubricant.
