"The Historical Atlas of World War II" by Alexander Swantson: https://www.amazon.com/Historical-Atlas-World-War-II/dp/0785831460/ref=sr_1_3?keywords=historical+atlas+of+world+war+ii+battles&qid=1580748278&sr=8-3

Here's some entertainment media if you're interested:
"Warlords" Documentary. Goes over the diplomatic and geopolitical games of chess that the various leaders of WWII played between eachother: https://www.youtube.com/playlist?list=PLegBT5TMS8994yANDPkV4id4dD8hY5PrQ
"World War II in Color" Documentary. This is a fantastic and great summary of the conflict at large, and features awesome, colorized footage from the era. I don't know how you best learn and absorb information, but I would advise watching this before reading any books so you are familiar with the events the authors are discussing and debating when you go reading them. Plus, you'll be able to visualize in your mind what is happening, what everything and everyone looks like, and the sheer scale of the conflict: https://www.youtube.com/playlist?list=PLJv4Ce9SBFaVrAi5fN08hFtyuNKHJKYFo
"1917" is a new movie out now in theaters which does a great job at showcasing what trench warfare looked like, and it's a very good fun movie.
"Saving Private Ryan" is a WWII film about the US D-Day Invasion of Normandy and France, and does a horrifying job depicting Operation Overlord. Purportedly, when the director did a private screening for veterans who were at Omaha beach, they collectively wept and were traumatized at the accuracy of the film to their experience. You might be able to find it on Netflix, Amazon, or other venues.
"Generation War" is a massively controversial German television series which depicts German soldiers on the Eastern Front during WWII. It's a fun war series, but it garnered immense criticism for its portrayal of German soldiers and other aspects, from historical military authenticity to misrepresentation. I haven't seen too much of it, but I think it would be a dual-valuable viewing in seeing a depiction of what the often overlooked but pivotal Eastern Front looked liked and an interesting exploration of the field of historical memory ("memory" is the academic field of how societies or communities collectively remember the past, as opposed to the "experience" of people who lived through the events personally and the "history" which professional historians interpret the past) in contemporary culture. I think you can watch it on Amazon Prime.
This suggestion depends on your interest in somewhat complicated board games, but "Axis and Allies" is a simulation of WWII between players. There are many versions, but "Axis and Allies: 1941" is cheapest and designed for beginners. Just a suggestion if you're interested in playing WWII games that aren't video games (which I'm sure you already are familiar with): https://www.amazon.com/Avalon-Hill-Axis-Allies-Board/dp/B007TB3R80/ref=sr_1_1?keywords=axis+and+allies&qid=1580749604&sr=8-1

You also mentioned you were interested in European military history in general. Here are some other ecclectic things I thought of:
"Napoleon: A Life" by Andrew Roberts. Arguably one of the most comprehensive works on Napoleon to date: https://www.amazon.com/Napoleon-Life-Andrew-Roberts/dp/0143127853/ref=pd_sbs_14_t_1/136-8743581-2515648?_encoding=UTF8&pd_rd_i=0143127853&pd_rd_r=0affd4ec-3e25-460b-b399-4bcb422598ad&pd_rd_w=nourR&pd_rd_wg=rvp7a&pf_rd_p=5cfcfe8...
"The Essential Thirty Years War: A Documentary History" edited and translated by Tryntje Helfferich. A brief reader of the Thirty Years War, one of the most destructive wars in European history which turned the continent into an actual interpretation of hell and killed millions on a scale and degree never seen before and never repeated in proportion again until World War I. The last of the Holy Wars and a massive conflict which then fully ushered Europe into the modern age with massed military conflicts and the utilitarian ubiquity of secularism. This book takes select documents, treaties, and (most interestingly) accounts of the war and adds exposition to each to explain the conflict. It's a short read, and the account by a soldier at the end of the book is by far the most interesting (he went from common soldier to high ranking officer back down to soldier, amassed considerable wealth and lost it in months, married and then wife and children died, switched sides, etc. each and all multiple times throughout his 10+ years fighting in the conflict): https://www.amazon.com/Essential-Thirty-Years-War/dp/1624663494/ref=sr_1_1?keywords=the+essential+thirty+years+war+tryntje+helfferich&qid=1580748499&sr=8-1
"The Franco-Prussian War" by Geoffrey Wawro. I'm told this is one of the best non-European works on the conflict: https://www.amazon.com/Franco-Prussian-War-German-Conquest-1870-1871/dp/052161743X/ref=sr_1_1?keywords=wawro+franco+prussian&qid=1580748827&sr=8-1
"On War" is an incompleted work by Carl von Clausewitz, largely considered to be the one who codified theories on modern warfare. This primary source is essential to having a robust knowledge of European military history: https://www.amazon.com/War-Illustrated-Carl-von-Clausewitz/dp/1686302487/ref=sr_1_2_sspa?crid=1CN614P367PY8&keywords=on+war+clausewitz&qid=1580749789&sprefix=on+war+clau%2Caps%2C149&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhb...
That's it for now. Like I said, I'm just throwing stuff intermittently as I think of it.
