Here we have a combined list of the 5 major critics lists generally considered canon. I've added to this a full listing of all the films included in the 12 lists found on your Letterboxd stats page.
There is, of course, a fair bit of overlap and naturally those duplicates are removed here. This creates a fairly sizeable list, something that if you can complete, you will have seen a huge amount of great cinema from all around the world.
I'd consider this the ultimate of lists. If you can watch all of these, you will have attained a breadth and scope of cinematic viewing and knowledge that few would have gained.
