Any ideas what (global) optimizers are well-suited for my case, especially when fitting noisy data?

There was a related discussion a while ago:

Global optimization: Simulated Method of Moments

I work with non-linear models that need to be calibrated to match data moments. The setup is simple. I have a function that takes a set of parameters as input (for example, a vector of floats), solves the model, and returns a measure of the distance between the model-generated moments and the data moments. Typically there are more moments than parameters. Hence, I use some simple weighting function to summarize the differences between model and data moments into one float. The objective is to m…
