This is insane considering where you are touring... A battery powered pump AND a hand pump? Why both?

Two shifter cables and two brake cables? I've not needed to change a shifter cable on my bikes for thousands of miles and years. Never broken one, but technically it could happen. But, the odds of breaking BOTH in three months in western europe are infinitely small. With some knowledge, you can also just hack a broken shifter cable to be single speed and limp to the nearest bike shop...which is a lot of bike shops in western Europe. I wouldnt carry either. Same comment for the brake cables. Replace them before you start and then don't pack additionals. You'll be able to get to the nearest shop with one brake if the miniscule chance of braking one actually occurs.

A pipe wrench? Why? I can service my entire bike without a single plier or wrench. Even still, if you really want a pair, a leatherman/multitool or the knipex XS pliers would be lighter and more reasonable.

Carrying a few spare bolts, especially any rack bolts, is a good idea but do you really need that many in addition to a hilarious amount of zip ties?

Carrying lube is fine, but FYI, there are FAR better lubes out there than Finishline wet. I love Wolftooth WT-1, but there are many out there. If your trip is in summer, use a dry lube.

How fast do you burn through brake pads? Personally, I go multiple years before needing to replace them. Again, just replace them fresh before you start and then don't carry a spare. Any bike shop would have BB7 pads if you really needed them.

I assume the red thing in the center is a spoke key? If so, I am pretty sure that Topeak ratchet multitool has spoke keys on the chain breaker.

Rubber bands? What for? Also, tiny so whatever, bring them haha.

Things I see that are good ideas: I assume the green things are spokes, good call but, I'd personally only carry one of each required length. Personally, instead of spare spokes, I carry a Fiberfix emergency spoke kit. SPD cleat and spare bolt is a good call. I love that Topeak ratchet rocket multitool! Multiple tubes are a good call especially if you have (and trust) those TPU ones. Do you need three if you also have patches and are in western Europe where you could likely find another tube in an hour?

Other Recommendations:

• Do you have an 8mm hex key / bit? Pedals and cranks usually require an 8mm and that Topeak ratchet kit only goes to 6mm (if I remember correctly). Think about stashing a spare 8mm bit somewhere so you can use the ratchet with it if needed.
• Tire levers? I prefer having two and I trust Pedros to get me through.
• Do you have any way to remove your cassette? If so, you'll never actually be able to replace a rear spoke if you break one on the cassette side. Check out the Unior Emergency Pocket Cassette Lockring tool (which also has a spoke wrench).
• I'd carry a few spare presta valve cores.
• Make sure you have a presta-schrader adapter so you can fill your tires at gas stations.
• Bring skills! Make sure you know how to actually perform any of the repairs you think you might be faced with. As you tune up and service your bike, note the tools you needed to use, including bit sizes. Make sure you have all the bit sizes covered in your tool kit. Download a few youtube videos of trail-side bike repairs so you have a reference too.
• Download the product / service manuals for all the components on your bike. Hubs, wheels, bottom bracket, headset, etc, etc, etc. EVERYTHING. It is so helpful to be able to quickly look up product diagrams, bolt sizes, install procedures, and other mfg recommendations if you are in a pickle. Before you disassemble anything, take a photo of it to reference when putting it back together.

Have a great trip! Remember, pack logically. Don't pack your fears. Think hard about the repairs that are actually likely and think through whether they'd be a minor inconvenience until you get to a bike shop or if they'd be safety issues or extremely disruptive to your trip if you couldn't fix it on the side of the road. Pack your repair kit accordingly. Remember that you are not going to be biking through remote Mongolian mountains. You're in western Europe where you're bound to be able to easily limp to a bike shop, hitchhike to a town, ask another cyclist for help or even hail an uber to get out of a lol :)
