How lightweight are strings in Emacs, if they don't contain any
properties?
Is there support for lighweight strings?

If you look at emacs/src/lisp.h and search for Lisp_String, you'll see
that strings are represented as a 4-word object:
- size in chars
- size in bytes
- pointer to text-properties interval tree
- pointer to the beginning of the string's content
