alt Hacker NewsI'm super biased in favor of iced.
Yes, there are missing features (it's not even version 1.0 yet!) but I think the number is very small now and the solution is usually to fill in the gaps yourself—which is possible because iced is totally modular
I've made a spreadsheet editor and a slideshow editor with it so "slimmed down photoshop" seems feasible although admittedly you will likely need to get deep into the renderer (possibly write your own renderer traits and there), but I suppose you're comfortable with that given your goal.

No support for RTL or CJK text, IMEs, or accessibility tools leaves it pretty firmly in the "toy" category for me for now, sadly.
This isn't meant to bash on the project specifically, basically the only tools that meet that criteria are platform native UIs, the web stack (including Electron), Qt and Flutter.
AccessKit is promising to change that but I haven't checked in a while how it's going. I did see GTK looking into it as a cross platform option as GTK's accessibility support only works on the Linux desktop currently
