I have not carbonated any of my meads yet. Not sure if I ever will either. I did cold crash some in keg, in the brew fridge before. Was able to bottle direct from keg (didn't have the beer gun or anything else at that time).
I'm giving my [14%] batches at least 10-12 months before going to bottle with them. I have batches started last December, that might be bottled soon. I suspect they won't go to bottle before it's been a full year, though. Just because things happen.
IMO/IME, time is one of your best ally's/tools you can have for mead. Having a kegging setup means you can get it super clear and then carbonate with the forced method (I would use the slow method, not rapid) and not get sediment forming in the bottles. You'll still get some stuff to settle out in bottles, unless you filter it. No harm done though.
