Confession time: I haven't watched much of Original Trek beyond the 6 movies, apart from a few of the more iconic episodes. I was able to follow those movies and get the gist for that cast just fine, and Picard had those same vibes as that. I could show this to my nephew without forcing him to sit through TNG every day after school and discussing it to death like my own aunt did, like geez I'm 12, lemme watch the Disney Afternoon FFS.I have to disagree...there is dialogue addressing every point you mention in your first paragraph in the first episode. It does assume some degree of familiarity, but then...it’s Captain Picard. Even outside of Trek circles it’s an iconic character.
*AHEM*
Anyway, yeah. We get enough backstory to describe the type of man he is and why he was so revered. The scene with the reporter and his correction of the "Romulans lives" bit shows us who he is and what he stands for without having to know of his defense of Data in season two or his own personal struggle to respect Hugh's autonomy and defy Starfleet's request to commit genocide to a people who had violated him the season before.
Now, if this were, say, a spin off on post DS9 Kira Nerys or Harry Kim* or a series following Trip Tucker's novel adventures, then yeah the audience might need a few more details to get invested, but the majority of folks tuning in will have some passing familiarity already.
*To be fair, the poor bloke was so shafted in canon, even Trek fans would need a lot more backstory in such a case
