I found the Fractal design ION+ 860W 80+ Platinum, with so called "Ultraflex" cables that sound just like the solution to my problem. Anyone know anything about this PSU?

IIRC the high end IONs are alright on electrical performance. The "Ultraflex" cables just sound like stock cables with extra steps though.
If it's perfect length you're looking for, you'd be hard-pressed to find anything out of ordering custom length cables (eg what I did for my SF600). But there's not a lot of reference to go off of, because most people who need custom lengths are building SFF, and most ATX/mATX users find an empty space in the case to stow the excess. The point of the off-the-shelf Cablemod stuff is to be easily able to fit most cases.
If it's softer cables you're looking for, custom cables is the only way to go. Seasonic stock cables are damn stiff. I have custom Modflex on my Corsair SF600 (a custom config I ordered back in 2016 or so), and a Modmesh (SE-series) on my Seasonic SGX650. Both are fantastic, pliable and easy to work with.
Your best bet is to get something that's widely supported from Corsair or Seasonic and either find a Cablemod kit you like, or place a custom order with a place like Pexon or Cablemod's configurator. Unfortunately, while the small vendors do some amazing work, they're hella expensive, work on a per-cable basis, and usually have a long wait time.
I think aside from their website Cablemod has a bunch of distributors around the world, take a look to see if there's one with stock that can ship to you. I think the reason they're all out of stock is they have no production at the moment due to factory upgrades.

I guess if you're just after softer cables and don't expect to ever get any custom cables in the future for this PSU, you can give the Fractal 860W a try.
