you have really small overlay icons in the Icon HIG we define to have at least 6x6px overlay icons. I add two emblem icons for select folders (emblem-added) and remove (emblem-remove) please use this two icons in the plasmoid Reproducible: Always

We also need an icon for the "open this folder in a popup" icon as the currently half-filled circle is pretty non-descriptive
That's not how this works, sorry - the action overlay icons come from the widgets/action-overlays SVG in the Plasma theme, they're not part of the icon theme. The size is units.iconSizes.small, which seems appropriate for this use case (it's 16x16 on 1.0 scaling, 32x32 on 2.0, etc.).
As the icon come from the plasma theme i will have a look there. About the open the folder in a popup i will make a bug report, cause plasma is focused on office users and will make things done. The popup thing is only in the desktop layout. It is fancy but used anywhere else. And the behaviour is different than in the icon view where you have the go up `folder` this is much more intuitive than the overlay stuff.

It's generic theming. The SVG contains elements with names like "remove", "add", "open" that the Folder View code uses, but it's available to all widgets.
should or can I make them more less generic?

I did exactly that to plasma-framework a while ago.
