FAST AND EASY PROCESS - 1 Step solder and seal process for all your connectionsWATERPROOF - Insulation tubing has unique dual-walled design: polyolefin tubing on the outside and hot melt adhesive inside. When heat is applied, polyolefin tubing reduces in size and adhesive flows inside the insulation. Dual walled tubing ensures waterproof seal and prevents wire corrosionEASY IDENTIFICATION - Color-coded tubing makes it easy to identify the right size of the connector for every application. Measure your wire, and easily choose the right connector by looking at wire size chart on the box.COMPLIANT WITH ALL RELEVANT STANDARDS - Our heat shrink connectors are compliant with ROHS, ISO 9001:2008, SGS and CE standards.WIREFY BRAND QUALITY COMMITMENT - We stand behind the quality of our products.

Jesus, have you never heard of insulated butt splices? Solder-and-seal connectors are even better.
You can solder or there are a variety of solderless connectors out there. A lot of people take the opportunity while they're replacing the fan to add in some type of connector (JST is popular and fine for something low current like a fan) to make any future swaps easier. If you're a bit timid about soldering you can use something like this - solder shrink connectors. I've never used them but have seen folks on another printing group recommend them. They're pretty much just shrink wrap with a bead of solder in the middle, you just stick the two wires in and heat. It solders and shrink wraps them all in one easy step.
I don't have any experience with any other crimpers than the ones I mentioned above but these are pretty highly rated. You might also consider using heat shrink/solder butt connectors. I've got the kit I linked to here and have been impressed with it. You will need a heat gun though but no crimping involved. Just use enough heat to melt the solder and shrink the heat shrink .
If it doesn't have to be something that can be disconnected easily, then this might work: https://www.amazon.com/dp/B01M0EZBYQ
Practice on some spare wires first. Takes a bit of trial and error, but then works great.
Not being able to disconnect might be against code. But then, it's only low voltage. So, probably not a big deal

Which wires specifically? In general, I was planning on going for heat-shrink solder terminal connectors and crimp connectors.
One of the reasons I posted this is because there are quite a few connectors and I am still not entirely 100% sure what I need. Obviously when screwing something in to a screw terminal block, the ring crimp connectors. But when joining wires, I would prefer to use the heat-shrink-solder type, but there are also butts and blades (heh).
I bought this set of terminals, figured I'd need them anyways: Assorted crimp terminals
I am probably going to buy this set of solder terminals: Fancy solder terminals
I am pretty good at soldering (though usually circuit boards, not automotive wires, hence not entirely knowing what to do.) I have easy access to a heat gun as well.

Well, both - the breaker goes on the battery, and it sets the maximum amperage for the entire new fuse block and everything attached to it. The fuses go for each individual circuit. I want to use just one fuse for each circuit, instead of having several different circuits sitting on the same fuse, largely for my own desire for neatness and debug-ability. I could have one main fuse instead of the main breaker, but I figure that they will serve the same function and I may as well go for the re-usable option.
I was going to go for this breaker: Fat breaker
That said, I bought this fuse kit, which includes up to a 35A fuse, which will be more than enough. I also bought this fuse holder, in case I decide to use one main fuse instead of one main breaker. (I figured I'd need both of these anyways for some project, may as well get them even if I don't use them right now.)

In general, I think my system will basically look like this:
Battery 12V + Breaker = safe 12V
Save 12V + ignition 12V (do I need a fuse here?) + Relay = ignition-switched 12V
Ignition-hot 12V + Fuse Block + ATC/ATO Fuses = eight fused circuits
Fused circuits, obviously, feeding from above. I will probably add a 20A switch in line with high-power circuits, just in case, as an emergency switch.
Fused circuits will terminate at something like this Ground Bar.
 
What do you think of this proposed setup?
I do realize that it's kind of overkill for what I want.
But you can probably agree that overkill is better than your car burning down!
