When I can count one piece as another, can I change that mid-action? (eg: counting Many Minds Move as One's sacred sites as a Beasts?)

Not generally, no. Unless otherwise specified, the rule for "You may count Thing X as Thing Y" is that you choose per piece, per action, and your decision applies for that whole action.
You can choose differently for nested actions - eg, if you flip the Blight card and it has immediate effects. (Example: You play Insatiable Hunger of the Swarm, and count all of your Sacred Sites as Beasts. It adds Blight which flips the Blight Card, revealing the one which destroys 1 Beasts on each board. You choose to not count any of your Sacred Sites as Beasts for that. You then continue resolving Insatiable Hunger of the Swarm, and your Sacred Sites count as Beasts for it.)
