Upgrade From Kaby Lake, Take II (!)

That looks like a very nice build, you should be able to set basically silent fan curves.

PCIE 5 SSDs are coming down to mortal prices, which may be worth looking at. Crucial just released their new model, and there is only about an $90 price difference between the Samsung 990 and the Crucial T705 at 2TB on Amazon (or $80 for the T700). It surprised me how much of a difference a faster SSD makes (I never expect that to make as much difference as it does for some reason).

G.Skill has developed a reputation as the preferred RAM vendor on AM5 if you want a problem free build, however I do not think this matters so much if you have any inclination to set timings yourself. That is pronounced enough that stores like MicroCenter advertise that the memory is by that vendor in their AM5 bundles though (which is unusual as they mostly only show speeds, and they have done this consistently recently.)

Also, while you do not strictly need a bigger PSU, if silence is the goal you may want one. Some can turn the fan off at low load, and low is usually a percentage of output as well as a temperature reading. The 1000W Corsair PSUs can do about 400W without the fan turning on for example.

If your chassis fans have been in there since the KL days, I might think about renewing them, especially if they are the original ones that came with the case.

The cooler on that GPU is going to be excellent but it is still a power hungry card, and will be dependent on good airflow through the case to get that heat out.

Of course it depends on what fan config you have in there now, but from my experience running a similar thermal load in the slightly bigger Define S, you'll ideally want a couple of exhaust fans at the back (120mm back, 140mm top) and maxing out the intakes at the front (x3 120mm / x2 140mm), to get enough throughput without any individual fan having to spin up too much.

You probably want the version of the SSD without the heatsink, generally the motherboard has one it should use.

Yeah, I filled all the chassis fan spaces back during the system build in 2017 with various adjustable speed Corsair fans. I'm actually annoyed chassis fans plug directly into the motherboard. To me, cases should have a form-factor standardized fan controller board with all the chassis fan power and speed controllers rather than the motherboard maybe having all the requisite connectors or maybe not.

I don't know that there is enough consistency between motherboards and cases to develop such a standard, although I like the idea. I'd look into some fan splitters so you can run your intake fans off one header and your exhaust fans from another?

Fractal, Phanteks, etc. have all had built in fan expansion hubs but they're mostly just PWM repeaters/replicators or a PWM DC follower, with independent power. Unless you want complete control of every individual fan they're good enough, and 3rd party versions for similar functionality are sub-$20.

Anything more complex than that would probably blow the BoM out of the water once you have to deal with shipping sensor data from the motherboard, a backhaul channel for programming/control, etc. There's probably a reason that we're literal decades into various fan controller efforts: bigNG, various aqueros/*adjust, Sunbeam Theta, the Corsair Commanders, Lamptrons and more I'm probably forgetting. And they've all remained in their niche.

Well that's what the various standards like ATX are supposed to do. Having a case-specific interface board (something just large enough to mount connectors and maybe a small chip) would eliminate the need for motherboards and cases to match each other.

I just don't think there is enough incentive to develop such standards, given that the 4-pin PWM fan header is the widely accepted de-facto way of running fans, and splitters are cheap and readily available for common use cases. As @teubbist says, lots of cases do have fan splitters and for most use cases these are perfectly sufficient. For "cooling enthusiasts" many other niche solutions exist, but they are always going to remain niche because not many people really need them.
