Really great and clear write-up.
For feedback: I wouldn’t say this isn’t a meta-analysis in the technical sense and it doesn’t seem like a systematic synthesis either. I think it’s a great intro to some prominent ideas with a more descriptive slant overall, though the places where you do evaluate evidence (e.g. Maslow re: lack of empirical evidence) are where the highest value would come for a reader who doesn’t know the literature. I think if you were to frame this differently and draw out a little more why we should care about wellbeing, you’d get more punch.

For flourishing, I think you’re missing some of the context with Barbara Fredrickson’s work, particularly broaden and build theory, which many people view as a major early contributor to this field .
Other important theories that come to mind withing positive psych or wellbeing:
Flow—notably the work of Mihaly Csikszentmihalyi
Grit—Angela Duckworth (although some folks think grit is basicaly conscientiousness repackaged)
Beyond PERMA, there are now a lot more mini-theories dealing with disposition, attitudes, character, gratitude. Sonja Lyubomirsky comes to mind with her theories on happiness. I guess it depends what you want to capture.
And more broadly for anyone wanting to read more into this literature, I think there are good recommendations for reading in these syllabi:

If you listen to Marty Seligman’s early talks, when positive psychology starts to become a more well defined field, his view of wellbeing is going beyond ‘the basics’ of everyday life. He’s even used numbers to say, ok if the aim of therapy is to bring a depressed person from −5 to −3 or 0, the goal of positive psychology is to take you from +3 to +5. Some wellbeing theories inherit this general thinking, and many of the basic physiological needs like having food or shelter or being safe are things seen for a requirement to be at a normal baseline. With the exception of social relations and some of the emotions work, you’re more likely to see most physiological needs in the clinical literature and some with folks who work on resilience.
