Well, traditionally, all metaphysics means is that it is beyond/after physics.  It's actually a bit of a misnomer in that we didn't know what to call the works after Aristotle's "Physics", so, we named them after (meta) physics.

When I said that I have a metaphysical goal of being a better person I mean my soul, who I am, wishes to be better to those around me.  This is not a science and beyond anything physics can describe.  One might say this is an ontological pursuit in that I am searching for my own definition, the definition of those around me, and how these relate to one another.  In understanding this I hope to improve my actions - a practical goal of a spiritual (metaphysical) quest.

Another application of this is causation.  Learning how my actions effect the (material) world around me helps in my pursuit of being a better person.  If I murder my neighbor then I will (likely) go to prison.  If I use psychedelics then hopefully the effect of this will be a better understanding of myself and the world around me.

Both of these are using 'metaphysics' to understand/improve my life. Yes, with practical goals attached but viewed under the lens of metaphysics.
