You've left yourself rather open to the obvious question : if applying Marx's theory today is "easy" bar the arduous labour of "elaboration" then can you give us a clue, PLEEASE! believe me, ignorance is not bliss....
The question of applying Marx's theory of money to today's reality, possible only for those who already share the common ground that it was valid before the end of Bretton-Woods, is relatively easy, compared to having to completely revise/reject his labor theory of value, yes. On the other hand, I claim that it's not easy for us to think through Marx's theory of money even during the gold standard. Didn't currencies fluctuate with each other back then as well? Did governments directly exchange gold with each other? There are lots of questions (e.g. why aren't hamburgers money). It's difficult to formulate a good question. Achieving this will be a step forward. I think it's your and my responsibility.
Ignoring everything I just wrote, fact-hunting is fun. Did you know that the Bank of International Settlements used the ounce of gold as its unit of account even until 2003?
Does gold still get moved from the vault of one country to another in NY federal reserve?
Graeber mentions there is 5000 tons of gold from central banks all over the world:

What do we count as monetary base; only the paper money and coins in circulation? More in general, during the gold standard were currencies 100% backed by gold? Until the present crisis the dollar was about 50% backed I reckon by gold.

Do central banks today in fact hold much more gold compared to the pre-world war 1 era, and why is that or how did this come about?

I don't care what you say.
Well, actually I think you generally add useful stuff to the conversation.
Just avoid the turn of phrase that imputes to others opinions that they don't actually have (or at least avoid with regard to me). Then no one will complain.
Simple?
