Card games and board games. Slay the Spire, Inscryption, Magic the Gathering, Yu-Gi-Oh, poker, chess. Golf. Tabletop RPG's like D&D.
It can get kind of hard to define "single thing" though. In Chess you have a ton of different pieces but can only move one per turn, while in D&D one character might get an action surge or have a familiar that gets actions. In Slay the Spire you have just one character but a handful of different cards each turn.
I would also consider a lot of adventure games and visual novels to be mostly turn-based. Like the original version of Myst, the Ace Attorney series, Sucker for Love.
Transistor is a kind of hybrid between real-time and turn-based, and you only control Red in that.
