Point taken. I didn't mean to imply that they were not possible as your extract from the corpus from what appear to be literature, academic, and news registers clearly shows.
However, it appeared to me from the context of the poster's question that we were assuming a 'business' register and as such aiming for succinctness and appropriacy within this context.
And in a business context I don't believe that 'and so forth' and 'and the like' would be very well received in a written form when collocated after 'He has advice, suggestions 'and so forth' for you.
So being context-specific, I don't think that it would be appropriate here.
We should be corpus-informed, but not necessarily corpus-led. Corpora do provide a wealth of useful information for us, but as yet I've not seen any that include the business register. They tend to be broken down into the fiction, news, academic and spoken registers (as the examples in your corpus extracts confirm); which although very useful for understanding usage across these registers, does not necessarily reflect appropriate usage in the business (English) register.
As I said, I assumed a specific business context and therefore register, and not a 'generality' in the question.
Apologies if my assumption was wrong...
