The word you're looking for is 'eudaimonia'
This post by JA Westenberg is about the 'middle path' which they equate with the Buddha, but which I'd associate with Aristotle:
We talk about the boring middle. The lazy middle. The compromised middle. But I put it to you that our obsession with picking the extreme and laughing at moderation is little more than cope. It’s our obsession with tribalism, with extremism, with feeling over thinking, with belonging over being. It’s destructive, unhelpful, and soul-destroying.
But it’s also easy. It’s easy to pick the simple answer of going all in on something, anything - of becoming pilled - of picking the red team and accusing the blue team of anything from immorality to inhumanity. It’s easy because all it takes is raising a particular flag.
The middle path is a good deal harder than any of that, and choosing it takes character, more than compromise.
It's interesting being my age (45) and being the parent of someone my son's age (19) as I can remember what it felt like to be that age, and how I thought about life, the world, and everything. I'm pretty sure 19 year-old Doug would be proud of some of 45 year-old Doug's achievements, but be a bit disappointed with what constitutes my current idea of "flourishing".
Verbally there is a very general agreement; for both the general run of men and people of superior refinement say that it is [eudaimonia], and identify living well and faring well with being happy; but with regard to what [eudaimonia] is they differ, and the many do not give the same account as the wise. For the former think it is some plain and obvious thing like pleasure, wealth or honour...
I guess, at the end of the day, I've moved from being a utilitarian to a virtue ethicist:
A utilitarian could accept the value of the virtue of kindness, but only because someone with a kind disposition is likely to bring about consequences that will maximize utility. So the virtue is only justified because of the consequences it brings about. In eudaimonist virtue ethics the virtues are justified because they are constitutive elements of eudaimonia (that is, human flourishing and wellbeing), which is good in itself.

To return to Westenberg, what 19 year-old Doug didn't realise is that moderation is harder than being extreme – in opinion, appetite, and exertion. When you're younger you're (usually) blessed with a body and a mind that are more able, more pliable, and less experienced. When you're older, you not only have the benefit of hindsight and experience in terms of how various ideas and pursuits affect yourself, but how they affect others.
The middle path is not the miquetoast [sic] average of two extremes; it’s not lukewarm, it’s not a compromise where you do everything by half measures and feel and accomplish nothing of substance. I find that version of the middle to be both reductive and somewhat cowardly. It’s a way of holding reasonableness and rationality in contempt, the favorite move of anyone who is pilled in any particular direction.
The middle path is the exhausting work of noticing - today, in this hour, in this moment, in this body, in this season of your life and your work - what moderation actually means; knowing the answer may be different next month, and knowing the responsibility for that moderation is yours and yours alone. There is no tribe that can make your decisions for you and make them easier to live with; no ideology that can forgive your sins or blame your failings on someone else’s flaws. The right amount of anything is a moving target that you have to find for yourself, again and again.
I think the reason that I was drawn to this particular post (I usually find Westenberg too declarative for my liking) is because I'm coming out the other side of a pretty awful experience of overtraining syndrome which very much showed me the limits of what this 45 year-old body is able to do. At the end of the day, I think wisdom is eudaimonic: Gandhi said that "Happiness is when what you think, what you say, and what you do are in harmony" but I think you could also substitute a Pragmatic 'wisdom' for 'happiness' there, too.
