By the way, I just built a Windows machine similarly spec'd to what you want right now. I got an off the shelf Dell XPS 15.6 1TB/32GB from Best Buy (14 core i9 12th gen, Nvidia 3050 Ti/4GB, 4K OLED touchscreen) and upgraded the RAM to 64GB and the storage to 12TB (4TB C drive, 8TB D drive) - you could also put 2 8TB in there too, for 16TB total).
Total cost, $4,000. If 16TB storage, $5,000. Apple has great laptops (I just upgraded to an M2 Pro Max, a modest 32GB/1TB), but the Apple luxury tax is high.
I feel you but I can't change OS anymore. First, I'm a slave to Mac (for good and bad reasons). Second, I'm a music producer and I have all my settings and VSTs tied to my OS and Ableton. Would be impossible for me to change.
Also I got accustomed to the way Apple is designed. I'd save 6'000 USD by going PC, but I prefer to pay more to keep my peace of mind (and nothing to tweak on my new MBP + TimeMachine = no time wasted).
