I have a few things that I can add. If you just want an adequate meal with the least amount of work, invest in:

* multicooker, one with a pressure cooking setting. You just have to press a few buttons and forget about it. If you know how much time it takes to cook something (for example - chickpeas, 26 minutes), you just set it for 26 minutes and go do something else. The multicooker will keep it warm for a few hours after it's done. No need to turn off the stove or anything like that. There's hardly any vapor released. You can make lots of dishes under pressure - pasta, lentils, chickpeas, beans... You can steam (almost?) any vegetable, as well. For beans and chickpeas the total prep time is hours, but the actual human time is minutes. Just put them under water for a few hours (takes ~30 seconds), then drain and put into the multicooker (takes ~1 minute). It takes a few minutes of actual work, but it also lets you forget about it, as it won't over-boil or anything like that. I can put something and go out, come back after a few hours and have a hot meal ready. I only use my regular stove top to make popcorn once in a while. The only downside is not being able to add different ingredients after the cooking has begun, as it's under pressure. And the "26" minutes above don't include the time it takes to reach the required pressure and the time it takes to release it. You can speed both steps by boiling water in a kettle before putting in the multicooker and by using the release valve after the cooking is done.

* bread maker - literally put water, oil, salt, sugar, flour and yeast one after the other, press a few buttons, wait a few hours and you get a perfect bread. Beats any recipe, including the "no-knead" ones, in terms of convenience. I can make better bread with lots of kneading and resting and whatnot, but the bread that comes out is good enough for me, so I don't see myself ever making bread by hand again.

If I lose all my possessions and have to rebuild from scratch, I would buy a cheap multicooker first, then a bread maker. Then, I'd think about a regular stove, a microwave and so on.

Another "optimization" is keeping everything in jars. Flour, coffee, sugar, cocoa, condiments, beans, oats - everything. It's much easier to see what and how much you have of everything, it's transparent, you can put labels on the jars (cheap price tags/stickers), you can pour from the jars easily, you can scoop with them with a spoon. No messy paper or plastic wraps. I don't get why people keep things in their original packaging - a bulky, wrinkled plastic or paper wrap that obscures the view behind it, obscures the view inside and makes it harder to scoop with a spoon.

For jars you use frequently, keep a spoon inside. I have a spoon in my coffee jar. I still have to get another spoon to swirl my coffee when it's done, so the sugar dissolves, but it's nice to not care about that when you're transferring the coffee from the jar to the moka pot or coffee maker.

And finally, keep similar ingredients near each other. The condiments, the teas, the legumes, the flours, the sauces. Just designate a place for each type of food. You can always adjust it later. In my cupboard the sugary condiments (sugar, molasses, xylitol, honey, etc.) are on the left, the salty ones are on the right (various types of salt, as well as salty mixes) and the other ones are in the middle (herbs and whatnot). Above that the most protein-y things are on the left, the cereal-y things are in the middle (oats, various seeds) and misc. things are on the right. The idea is that whenever I buy something, when I come home I immediately pour it into a jar and put it where it belongs. That way everything is pretty and organized. Queries like "how much lentils do I have left" are answered in seconds. The overhead of keeping the jars clean is minimal, as you don't have to clean the jars all the time - if you had a jar of lentils that's now empty, just leave it "dirty". It's not unhygienic, especially if you'll put lentils or other food that you'll boil in it later, anyway. I clean them once they get visible dirty - if I've touched them with greasy fingers, for example.
