I'm planning a new gaming PC to replace my 2017 system. My budget is around $2,000, and I'm buying in Canada. The system will mainly be used for occasional gaming, including games such as Company of Heroes, Call of Duty, and Red Dead Redemption 2. I may also play future releases such as the next Call of Duty and GTA 6 on PC. I currently have a GTX 1070 and a 1080p monitor, but I'd eventually like to move to 1440p or possibly 4K.
I'm considering a Ryzen 7 9800X3D or Ryzen 9 9950X3D, an Arctic Liquid Freezer III Pro 420 mm cooler, an ASUS ROG Strix X870E motherboard, 32 GB or more of DDR5-6000 CL30 memory, a Samsung 990 Pro SSD, a quiet fully modular 1,000 W power supply, and a spacious Fractal Design or Corsair case. The graphics card and monitor may be purchased later, possibly an RTX 5070 Ti or RTX 5080, so I'd like to use my GTX 1070 temporarily.
I prefer a quiet system with reasonable overclocking or tuning potential and would like it to remain useful for the next 8–10 years. Should I build the entire system now, or buy the CPU, motherboard, memory, and storage first and upgrade the case, power supply, graphics card, and monitor later? Which parts are excessive or poor value?

Your parts list spends heavily on components that do not improve gaming performance very much. A 9800X3D, 32 GB of memory, a 2 TB SSD, and a midrange AM5 board would be a strong foundation. A Radeon RX 9070 XT-class card is a good 1440p option if you decide to buy the GPU now, while a higher-end future card would make more sense for 4K.
For an 8–10 year plan, prioritize replaceable and reliable parts rather than trying to make every component last unchanged for a decade. Start with a good case, power supply, and motherboard, but remember that memory capacity, storage, and the graphics card may need upgrades later. A quiet tower air cooler is also worth considering because it has fewer long-term failure points than an AIO.
For a gaming-focused build, the Ryzen 7 9800X3D is the sensible choice. The 9950X3D only makes sense if you also do substantial productivity work, since most games will not benefit enough from the extra cores. You also do not need an expensive X870E or ROG motherboard unless you specifically need its connectivity features. A good B850 or B650 board with the features you actually use should be plenty.
DDR5-6000 is a good target, although CL30 is preferable if the price difference is small. A quality 2 TB NVMe drive is more practical than paying a premium for a flagship SSD that will not noticeably improve gaming. I would also avoid planning around a huge 420 mm liquid cooler: it is expensive, harder to fit, and adds pump-failure risk over a long ownership period. A strong air cooler or a simpler 240/360 mm liquid cooler should be quieter and easier to maintain.
The graphics card and monitor are intentionally outside the initial budget. I’d like to run the GTX 1070 for a while, then choose the replacement GPU and display closer to the next major game release.
The biggest issue is defining the budget in one currency and deciding whether the graphics card and monitor are included. If the full system, GPU, and display must fit within roughly $2,000, 4K gaming will require major compromises; 1440p is the more realistic target. If the GPU and monitor are deferred, you can build a much stronger platform now and reuse the GTX 1070 temporarily.
A sensible base would be the 9800X3D, a reasonably priced AM5 motherboard, 32 GB of DDR5-6000, a 2 TB NVMe SSD, and a high-quality 850–1,000 W ATX 3.x power supply. Put the savings toward the future graphics card rather than premium branding, an oversized motherboard, or an unnecessarily expensive SSD.

That makes sense. I was mainly considering liquid cooling for lower noise and some overclocking headroom, but reliability is more important if I plan to keep the system for many years.
