Similar recent-ish thread for android, most of which have Apple variants.
I’ll note I also mentioned Xcom in that that thread, so there’s a second to @Reply’s first suggestion!
I’ll also throw a second at Plague, Inc. I play/played that one myself far more than I should, and it’s pretty easy to pick up and put down, and I should mention it has “fantasy” elements available including mindworms and zombie invasions if you want to have a break from seeing if you can kill humanity the old-fashioned way.
I think it’s useful to narrow down what @RickJay prefers out of a strategy game. Tower, resource gathering, unit production, tactical movement, what have you.
