Wikidata has qualifiers and ranks which can be added to statements that can be used for this.
As an example, Barbados:
(statement) head of state (P35): Queen Elizabeth II (Q9682)
(qualifier) start time (P580): 30 November 1966
(qualifier) end time (P582): 29 November 2021
(statement) head of state (P35): Sandra Mason (Q9333540)
(qualifier) start time (P582): 30 November 2021
the second statement then has the "preferred" rank (the first has a "normal" rank, and there is also a "deprecated" rank for inaccurate information)
