I mainly contribute to French Wikipedia (Q8447) (see my user page w:fr:Utilisateur:PAC2) and I contribute to Wikidata since 2013.

In French Wikipedia (Q8447), I develop some Infobox which relies on wikidata such as w:fr:Modèle:Infobox Jeu de données, w:fr:Modèle:Infobox Discipline, w:fr:Modèle:Infobox Concept socio-fiscal, w:fr:Modèle:Infobox Politique publique, w:fr:Modèle:Infobox Méthode scientifique, etc.

I like explore wikidata with some notebooks. I have written User:PAC2/Ministres, User:PAC2/Portrait d'un prénom, User:PAC2/Economiste and Wikidata:WikiProject France/Administrations, User:PAC2/Tour de France, User:PAC2/Measuring gender diversity. I have recently discovered that Wikidata:PAWS provides SPARQL Jupyter notebooks and I think it's a good way to explore wikidata (see example).

Wikidata has subject-predicate-object model. Yet, Q item pages only show statements where the Q item is subject. The most interesting part of the data : statements which have the Q item as an object are hidden. SPARQL queries make them discoverable. However, SPARQL queries are really hard to write (even with some experience). Therefore I believe that there is a lot of value to develop generic SPARQL queries for each kind of item. So far, I've written some generic queries templates : {{Notebook Given name}}, {{TP administrative area}}, {{TP organization}}, {{TP award}}, {{Generic queries for occupations}}, {{Generic queries for genre}}, {{Generic queries for filmmakers}}, {{Generic queries for actors}}, {{Generic queries for positions}}, {{Generic queries for sports competitions}}, and {{Generic queries for humans}}. Those templates are embedded in {{Item documentation}}, a documentation template which can be added to every talk page of an item. I'm not sure it is the best way because very few people visit talk pages in Wikidata but I haven't found a better solution so far.

One major issue with Wikidata is ambiguity. There is lots of ambiguity in Wikidata. Even if you're experienced, you don't know if you have to use one property or another, etc. I don't know reduce this ambiguity.

I also develop {{Colorbar}}, {{SPARQL Inline}} and {{SPARQL Box}}, {{HasOccupation}} and I have created WikiProject Templates.
