Given a list of mixed items (numbers, numeric strings, nested lists of those, None) and a float multiplier, produce a flat list of floats: extract every numeric value (parse numeric strings), skip None, recurse into lists one level, multiply each extracted number by multiplier. Return the resulting floats in traversal order.
