Thank you @wfpeter! Installing your recommended Enable jQuery Migrate Helper plugin worked like a charm! That resolved issues #2 and #3 (Media Library in grid mode is now visible and the Wordfence plugin is working like normal).
As for issue #1 (comments unseen on my blog), well, I’m still in trouble there.
I tried deactivating all plugins and refreshing the website, but they still do not show up.
Here is my website:

Any thoughts/comments/suggestions off the top of your head?
Again, thank you so much for that first tip. It ended up lifting a lot of stress off my shoulders getting those 2 other issues fixed!
