The 400 nit panel has ridiculous amounts of ghosting (to the point where you can see it just by moving the mouse pointer), and the 500 nit panel is a “privacy” option which means worse than TN viewing angles. Unfortunately Lenovo is currently limiting the good screen to Intel for whatever reason.

Yup .. I was seriously considering buying one except for the ridiculous screen options!

The x13 has an almost acceptable screen but non-touch, and single channel ram issues if I remember right.

There just doesn't seem to be a really good ryzen laptop on the market. I'm vaguely hoping the MS surface laptop 4 releases with a nice surprise of reduced bezels and two pcie ssd slots!

The Yoga Slim 7 Pro looks great and has a color accurate retina-level display, but it seems impossible to actually buy one.

Yes, it's on my radar! I believe it's not released yet and likely to be early next year.

If you are not pressured to buy now I would advise to wait until the next year where Ryzen laptops with USB4/TB4 will hit the market.
