Very nice framework.

I think there is yet some other thing which has a bit of both your Meaningful and Value. Stuff that you decide you should do not precisely (or maybe precisely and this comment is just not well enough considered) because it's meaningful to you but because you just feel it should be done.

Maybe because you just recognize that someone has to do it and you should at least take your turn if not make it your whole life. Maybe because you want to live in a world where it gets done, even if you live in a society that doesn't provide for it to get done. (no one will pay you or anyone else to do it)

Phrasing these things as meaningful makes it into something someone else can say is simply your choice. If it's important to you, you can do it. And let you shoulder the entire burden for something they absolutely benefit from and should be pitching in their fair share towards in some form or another, if not tax money then time or effort, something.

It is definitely meaningful for some people, the people that are so moved that they actually give their time & energy, but those are people for whom it's actually a large part of their life & identity. I'm not like that. I am not going to volunteer for whole shifts anywhere. I care about a strangers problems intellectually. I care in the sense that I want it dealt with humanely with dignity as if I had the problem myself. I don't care directly and personally, emotionally, unless they are somehow close to me. But I would happily pitch in my fair share if we all were, because it would be small.

It's partially value because we all get value from living in the better world thanks to the various thankless tasks some people perform.

Eh, maybe I'm arguing up the wrong tree and what you expressed already covers this.

I am thinking something like "This thing should get done not because I derive meaning from it.", but really maybe what you're talking about isn't even trying to deny that. The point would still be that I might choose to commit a certain amount of my life capital towards something, because of a certain amount of value and meaning that I, let's say recognize not derive or get, from it.

I'm leaving out fun. You can have fun cooking soup for the homeless. I can not imagine having fun cleaning someone who can't clean themselves and can't pay you to do it.
