Help better understand Blendspaces

Yeah sorry, it’s confusing to me just because of the use case I am trying to use it for. So the game I am working on the player will not technically move as it’s a boxing game (the best example is the game Super Punch out on SNES). I only want to know if I should be using blend spaces to make my animation transition between each other smoother or if blend space is only useful for movements, walking jumping, etc. So is animation layering something available in UE5?
