If I guess correctly, your problem is that

\version "2.22.2"

reference = "1"
\label #(string-append "Ref" reference)


does not work? The issue here is that string-append takes
strings and returns a string, while \label takes a Scheme
symbol, which is a different beast (#"abc" vs. #'abc).
The reason why it magically works if the string comes from a
variable is a bit difficult to explain without going into
details, but it's pretty unusual to do it like this. Instead,
just convert the string to a symbol:

\version "2.22.2"

reference = "1"
\label #(string->symbol (string-append "Ref" reference))


Best,
