Question about Samsung Galaxy Tab A8

Hello, I find it a bit confusing when I want to buy the Samsung Galaxy Tab A8 SM-X200NZAAEUE and a matching protective cover. Then there is a choice here Galaxy Tab A8 and Galaxy Tab A8 (2021). Are these both compatible and fit the Tab? Then there is also the A 8.0, A 8.0 (2017), A 8.0 (2018), A 8.0 (2019) Which ones fit the tablet here?
