The dump files should contain all language content - Wikidata does not have different language editions and so there are no language-specific dumps. In general all items and properties exist in all languages - the difference is in the labels which are applied to them. (There are a few plain-text fields which are language specific, but not for things like "occupation")
The python library you mention is not one I'm familiar with, and it's confusing me a bit - WD doesn't give any particular priority or special status to English, but this only seems to return English labels/descriptions, which suggests to me that maybe it has hard coded a language selector somewhere. I wonder if you might be able to tinker with the code and just switch eg 'fr' for 'en' somewhere. I couldn't work out where that is set, though.
Alternatively, rather than use this API wrapper to get labels for a given property/item, you could try using and parsing the Wikidata query service results, or the Wikidata MediaWiki API - this will give you much finer control over languages returned etc. The WD data access page gives an indication of the various endpoints.
It depends a little on what you're trying to do - for "all properties and values on a specific item with labels in a specific language", the MediaWiki API is probably best; for "all values of a single property across all items with labels in a specific language", the query service is best.
