My guess is that a future Elements version, maybe not the expected PSE16 in the Fall, will have it. Microsoft and Adobe have been working together to provide seamless scaling for the UI, but we are still on beta testing for the full Photoshop. For the image viewing, you are zooming all the time anyway, it's the ease of use of the menus which is critical it depends from your hardware, but also on your own viewing aptitudes and tastes. Don't be mistaken: for photo editing lower resolutions are more comfortable and precise than HiDpi.

If both 100% and 200% settings are not good in your case, you'll have to set your display resolution to a lower value, like 1920 x 1080 or even less. Note that the scale factor is not used in the organizer, which can recognize the custom size font settings of the Windows explorer (125% for instance) Good for real 4k resolution and normal size desktop monitors, but 200% setting may lead to hide part of the menus and tool bars with too big fonts. I can adjust it by dragging the box, etc., and putting in small icons or just a list but it doesnt affect the actual menu size. For aspiring detectives and photographers alike, features like Super Resolution can quadruple the size of your photos using AI, giving you the clean edges and detail you need to make the most of any shot. It also happens when I open up a menu, everything is oversized. It may not be movie magic, but it’s pretty close. The solution provided from Elements 13 on was to allow the '200% UI Scale Factor. But today, Adobe Photoshop and Adobe Photoshop Lightroom have features that can help you increase resolution while upholding visual quality.

Since the introduction of HiDpi (or 4k) displays some 6 years ago, the way fonts are displayed in Windows has been a problem for softwares totally based on old Microsoft APIs they do not allow 'scaling' the menu font sizes freely.

Your issue is that you have a semi-high resolution and small display (the worst situation now.)
