I'm not aware of any other freely available, prepared sets of cross-references that can be used.
https://www.openbible.info/labs/cross-references/ has a list of over 300,000 references that could be used, but would need to be converted and cleaned-up to be useful.
Paratext includes an export feature that can be used on projects (not resources) to export references from another project.
Project menu > Advanced > Extract Cross References
You need to make sure that you have permission to use cross references from another project.
