I'm no build guru Chris, but that looks alright to me.
Am assuming you've considered the limited PCI slot availability tho (2 PCIe 4.0 ... 1x16 or 2x8) and that it's likely going to be enough for your needs for its lifetime? I noted on the mobo specs that the additional PCIe 3.0 x16 slot shares its bandwidth with the Thunderbolt ports (so you can use one or the other, but not both) and the 2 PCIe 3.0 x1 slots share bandwidth with the 2x M2 slots... probably not an issue if you're only looking to add a single graphics card and maybe also a Decklink card ... worth keeping in mind tho.
Graphics card wise, an RTX 3090 would certainly be a nice upgrade for the doubled VRAM it offers... but the 3080Ti is a heavy lifter and by the time its paltry 12GB VRAM becomes a limitation you'll probably be looking for a new machine or a next-gen graphics card anyway.
Not sure you need to worry about spending extra on 3600MHz RAM... its all about latency anyway and some 3600 RAM is slower than some 3200 RAM... and I suspect either way the real world difference is likely to be intangible ie a fractional percentage point. But if money's no object then faster is faster.
You could maybe consider a SATA SSD (single or RAID) for your OS and then use the M.2 NVMe storage for cache and data... or NVMe for OS and cache and use an internal SATA SSD RAID for data. Also maybe should be considering a regular internal HDD RAID for online archive/media libraries... or an external Thunderbolt one.
Spending other peoples money is easy tho ... as is, I'd say theres nothing inherently bad about the proposed config that should prevent you from working quite happily with 4K media.
Let's have a return to the glory days, when press releases for new versions included text like "...with over 300 new features and improvements that professional editors and colorists have asked for."
