Where possible, you may also add a wikidata=* tag. Any notable and clearly identifiable material entity is allowed to have a Wikidata entry (See Wikidata's notability guidelines). A Wikidata entity would contain a statement about an image, 3D model, Commons category, or Commons gallery being associated with the entity.
Adding wikimedia_commons=* to an object that has wikidata=* can be considered redundant because Wikidata itself often links to Wikimedia Commons. The vast majority of less experienced (newbies and occasional) users however is way more likely to understand the concept and importance of Wikimedia Commons than Wikidata though and that's why it can be considered good to add both. Even for experienced users, the human-readable value of wikimedia_commons=* is easier to interpret.
This can be useful for giving armchair mappers (some of which may be experienced validators) a better chance at understanding the object (a museum, unique house, bridge or memorial for example or even long distance cycle routes e.g. wikipedia=*, wikidata=* or website=* tags or other easily available sources.) and eventually complement or correct tags. Especially useful when the object doesn't also have

Common tagging mistakes
- Photo linking - Create links between OSM features and external pictures
- image=* - has simple syntax (File:*) for linking to individual images on Commons too, but is less safe.
- mapillary=* - link to individual image in the Mapillary database
- 3dmr=* - for linking 3d models on the 3D Model Repository
- wikipedia=* - provides a link to Wikipedia's article about the feature.
- wikidata=* - The ID of the Wikidata item about the feature.
