Updated Single Player info for Snapshot 19w06a

Below is the block of text that I use to setup a new Minecraft, Single Player game. This is what I have programmed into one of my Logitec, G910 Gamer Keyboard's command keys so that I can just press the one key and it will send all of these commands (takes a while to complete because I had to use a 50 millisecond delay between characters in order to prevent errors in Minecraft. I have some values set quite high so I get a lot of loot or mined items (such as diamonds or coal), but not so high that they will crash my game or fill the inventory too fast.

The first part sets up Game rules so that all of my creations don't get blown up or burned up by mobs and it lets me keep everything in my inventory if I get killed (which happens a lot when you are trying to demonstrate stuff for a video).

Next I give myself weapons, tools, armor, and a couple of additional items to make life easier. Here are the attributes that I use most:

Mending so that my items will automatically repair any damage they received:

{id:mending,lvl:1}

Unbreaking of 10,000 so that my items don't wear out or break on me:

{id:unbreaking,lvl:10000}

Then, depending upon what the item is used for, I either give it Silk Touch, Fortune, or Looting:

Silk Touch makes the item harvest/mine/dig blocks and leave them as they were, such as Grass blocks instead of dirt, ore blocks instead of ore, gravel instead of sometimes getting flint, etc. Silk touch is also used to gather things like Turtle Eggs.

{id:silk_touch,lvl:1}

Fortune makes your item harvest/mine with more individual items harvested/mined.. such as getting 64 diamonds instead of just 1 when you mine a diamond block. Or, getting 64 coal instead of just 1 when you mine a block of coal ore.  Perhaps you harvest carrots or potatoes with your hoe, you'll get a lot more if you have fortune instead of just plain. I use a value of 100 which gives me a LOT. If you set this higher then you can fill your inventory very fast, or possibly crash the game.

{id:fortune,lvl:100}

Looting is like Fortune, but it is used for weapons and it determines what or how much loot you get from a mob when you kill it. Higher values here will give you more of the "treasure" items.  Too high will fill your inventory very fast and possibly crash the game.

{id:looting,lvl:100}

Then I use Power for my Bow or Sharpness for my Sword. These increase the damage they do.

{id:power,lvl:100}

{id:sharpness,lvl:100}

I also give myself Ender Chests because I like to place them around while I explore.  I keep one Ender Chest in my toon's inventory to be placed, and the rest I keep in an Ender Chest that has been placed. When I use one, I open it and take out another to replace it in my inventory.

Then, I use Shulker Boxes inside the Ender Chest to hold all kinds of stuff from Mob Loot, Flowers (for dye), food, seeds, building materials, Wood, Ore, Nether Items, End Items, etc.  Each type can be placed in a dyed Shulker box so I can easily find it.

Note: OK, I have cheats enabled but I don't use them constantly, after all, the object of my playing a single player game is to learn about the different changes that have been made or to learn new stuff, not to just fill my inventory with new items or build some structure (thought I do experiment with those too).  My main game is online on the Minecraft "EndGame" server, where I do not use any cheats and I spend a lot of time mining for materials, growing trees/food/flowers/etc. or building structures (my structures are mostly square boxes of one kind or another). I also spend a substantial amount of time exploring for new materials like mycelium and terracotta.
