I know this doesn't directly address OP, but I encourage players to be okay with being "boring and fast" on their turn. If you cast a spell and stride or block, great! Just do it quickly. That way your next turn will come up sooner, and you'll have more fun. I'd much rather each player take 1 minute on their turn and us get through a battle quickly, than each player have multiple tricky "fun" things on every turn, and get through battle twice as slow.
So for me, I'm more concerned with others not trying to maximize the 3 actions than I am with Wizards not "getting the most" out of them.
