If anything, it is probably a good idea to keep accounts open for the next few weeks and check on them periodically to see if the content restores on its own. If it does, you can then proceed to use the delete suite of your choice and run it again.
I suppose that once you are fully confident in deleting your account, you can do so. Alternatively, it might be better to keep the accounts open but delete all the content at this point.
Wow... You aren't kidding. I wiped out a very old account I had from when I was far younger the other day. Logged into it just now and all my edits and deletions are back like it never happened...
