Question Motherboard for my next build

[pcm81]

Recently I've been posting a few threads about the next build, and now the plan is coming together; but need a recommendation for good mobo.
I will be using Antec 1200 case (i have one and bought another because i like it)
I will be using 1000W CORSAIR RM1000x as PSU.

I have not completely decided on the CPU, but am leaning towards at-least a $600 cpus like AMD Ryzen™ 9 9950X3D or Core 9 285K CU-8200 | DDR5-7200 or similar but better ~$1K CPU budget.
Well technically it is more like a $2K - $2.5K CPU+MOBO+RAM budget.
The catch is: I use a blue ray for back-up (90 nostalgia) and have multiple 16TB HDDs for storage. so that means i need a bunch of SATA connectors or PCIe slots for SAS/SATA card in addition to other cards.
I have been looking at MOBOs like ASUS TUF GAMING X870-PLUS but the modern DDR5 gaming boards i see seem to be lacking SATA ports and PCIe slots. Yeah M.2 is great but 16TB SSDs are expansive... plus i prefer swapable trays in the front bays.

Can anyone suggest some good boards i should consider? Perhaps i should be looking more at workstation rather than gaming boards?
DDR5+PCIe5 preferred for future proofing.

Reliability, stability and feature set are important. My current MOBO was like $300 in 2011, so when i now see $200 boards, after 14 years of inflation, i have to question what corners have been cut...
Thanks

What do you guys think about this one: https://www.asus.com/us/motherboards-components/motherboards/workstation/pro-ws-z890-ace-se/
Looking at the specs i like it better than the gaming boards I've seen earlier. Still trying to decide between intel vs amd; but board specs/features seem reasonable.

Why do you need these drives in the PC? Why don't you store these drives in a NAS? Are you constantly accessing this data?

Yeah, that seems like a tank of a mobo. Guaranteed to work 24/7 in 80% humidity is impressive. Price seems reasonable if your plan is to keep it for 5 years minimum.

Almost same features from AMD mobo (no BMC): https://www.asus.com/me-en/motherboards-components/motherboards/proart/proart-x870e-creator-wifi/

9950X3D is going to be a lot better than 285K, unless you have some specific workload that Zen 5 is poor at.

I built a tank of a pc in 2011, still my main pc today, original mobo, cpu, ram... this will be a similar build.

Because NAS is the 3rd copy. Two copies of data in computer, 1 in NAS and selected stuff also gets blue-ray back-up.
