I dunno… median OECD state modern person, or median modern person globally?

I might go with being one of the richer medieval kings, in the latter case. Global median is pretty bad.

Only things that might sway me otherwise are antibiotics and if we’re factoring in the whole “sword of Damocles” aspect for despotic rulers.

Global median is pretty good - out of poverty even by modern standards. And antibiotics and other medical care are definitely a large factor here, as well as the general safety that comes from living in a state with laws.

I replied here [2] to an essentially identical question. Basically, it comes down to a question - what do you want out of life? And are you going to be more able to achieve that as e.g. a king, or as somebody earning $45k a year in the US (the current median personal income)?

And again, it feels very obvious to me that the median modern life is better than a king in the Middle Ages. Unless your interests are leading a short hedonistic life being controlled by your court and meeting a violent end. But I don’t think most people would value that.

Going with what I said in the other post - I would like to: have a large family, plenty of social relations, and the ability to play a role in shaping the future of society. Am I more likely to be able to achieve this as a king, or as somebody in the US earning $45k/year? For that matter I can't really think of anything that would be easier as somebody earning $45k a year in the US. What are your aspirations in life?
