Tinned food will last for years, decades, quite safely.
In 1865 a steam ship called the Bertrand sank in the Missouri river. It was a freighter and had all the supplies, food clothing that inland frontier towns might want. The wreck was discovered in 1968.
In 1974, samples of canned food from the wreck, including brandied peaches, oysters, plum tomatoes, honey, and mixed vegetables, were tested by the National Food Processors Association. Although their appearance, smell, and vitamin content had deteriorated, there was no trace of microbial growth and the food was determined to be still safe to eat.
So I really would not worry about a tin stamped best before August 2023 - or even 1923!!!!!
