this is something i strongly desire for people close to me to learn

i dont think it sticks if i preach at them but think it would if i somehow engineered a way for them to "find out for themselves"

are there approachable resources (not Dave Ramsey, please) to make this stick?

I think this is something that's very difficult to learn. It's a set of attitudes more than anything, and it's very countercultural (and not in a cool way).

Mr money mustache isn't my favorite for various reasons, but he's pretty good at evangelizing the diy/fire sprit. Just take it with a grain of salt.
