The camera thing is what got me about the whole idea of players hitting pause or something during an enemy turn.

Larian's goal seems to be to speed up combat so much that you barely know what the flip is happening. Grove fight with Aradin. Camera jumped numerous times to NPCs and they had acted almost before the camera was on them. There's literally no time to hit spacebar or something to pause the enemy turn to react.

I agree that the best solution is most likely the Solasta/Composer one on the Megathread. It gives absolute full control to the player, and as Niara had pointed out, reactions only cause prompts when the right conditions are met. It isn't constant or even super frequent.

Also, Reactions done properly actually allow players to play the game during enemy turns instead of always just watching the game play out. Although I still think presets could work, it is as a few said at one point. Presets mean you just watch the combat. Prompts mean you get to participate. So presets, imo, would be a secondary option if for some reason prompts that interrupt would be the primary solution.
