Victoria 3 for me so far has been staring at the building screen. It's far more of a economy management game than a war game. There is definitely not as much character based stuff as in CK3, but there are occasional events and traits for faction and army leaders do affect several things, but you wont get some naked lunatic deciding to marry his horse. The warfare is very simple surface level, but the general system is a bit confusing at first. Also the game in its current state has a slightly unhelpful UI, tooltips not giving tips, hidden stats, decisions buried under tabs, the profit calculation being straight up wrong, etc.

What I'm trying to say is that it's not as complex surface level like EU4 or HoI4 and I recommend trying a couple of games as New South Wales in Australia (tutorial island, featuring gold rushes, colonization, immigration, a big market to support you, few to no enemies) or the USA (massive resources, a bit of warfare, some diplomacy with the UK and Colombia, politicking to get rid of slavery, very straight forward after the potential civil war.) and see how it works out.
