Retrieve only one label from set of individuals with multiple labels

Suppose I have the following set of individuals, where some of them have more than one rdfs:label:

Individual Label
ind_01 "ind-001"
ind_02 "ind-002"
ind_02 "ind-2"
ind_03 "label3"
ind_04 "ind-4"
ind_04 "ind-04"
... ...

I would like to run a SPARQL query that retrieves only one label per individual, no matter which one (i.e., the choice can be totally arbitrary). Thus, a suitable output based on the above dataset would be:

Individual Label
ind_01 "ind-001"
ind_02 "ind-002"
ind_03 "label3"
ind_04 "ind-4"
... ...

You could use SAMPLE, which "returns an arbitrary value from the multiset passed to it".

SELECT ?individual (SAMPLE(?label) AS ?label_sample) 
WHERE {
  ?individual rdfs:label ?label .
}
GROUP BY ?individual
