IMO, you just choose what YOU like, what YOU want - some of that, at first, will be overlays from various inept social programming that was handed down as good for the masses, but maybe flawed in some way, so it’s good to do what the 12-step cults call a “fearless moral inventory” and also, be psychologically literate, strive for insight into yourself, your motivations, choices, and patterns you repeat, and so on.
I cleansed my mind of the toxic nihilism of the RHP and “altruistic” programming by doing this, and I can vouch or the process, even if it lands people at diferent results and different value systems.
Regarding wider morality, if possible expose yourself to various extreme political (and religious) views occasionally, and attempt to place yourself in the mindset of the people who hold them, and figure out what the “perfect world and perfect outcome” would be like, if they suddenly prevailed. Does it suit you? What are the drawbacks? (And so on.)
I was VERY lucky to be taught that last as a thought-exercise by my parents, and it’s stood me in good stead and allowed me to explore mindsets that I deplore, and yet feel less “victimised” by, because I now see what they think they’re going to get, but most usefully, I’ve explored by immersion those that I find beneficial and empowering, both in an everyday sense and also, as conscious choices within a world of illusions.
(To explain that last, going to copy-paste something I’ve mentioned on here before: "This is discussed in the Kybalion as the Divine Paradox: the infinite All witnesses the universe as a dream; the finite (us) witnesses the universe as real. To think as God is to be in a state of detached “mountain-top consciousness” which is incompatible with everyday life and everyday consciousness with desires, hopes, etc.
The universe is; and is not - these two poles of truth are the Absolute and the Relative…")
As for hedonistic pursuits - are they harming you? If so, handle that appropriately by looking at what the payoff is, how that fits with your models of time, of self as needing consolation (a legit but damaging concept that fucks many people up with chemical and behavioural addictions) and so on.
And, are they harming anyone you consider to be, for want of a better description, a protected group? (For example, I’m opposed to eating dogs unless you’re in seige conditions, becaue they’re faithful to humans and will save our lives even when it costs them their own, and will generally be sources of love and joy, but I do condone eating cattle, providing that they have good lives and humane deaths. Everything is conditional, everything is about personal value systems and personal preferences.)
JMO on this and I’m no philosopher… which is probably pretty obvious!! lol!!!
