I like John Vervaeke's meaning-in-life questions (potentially mildly paraphrasing, because it has been a while since I came across them):

- what is it that I want there to be more of in the world, even after I'm gone?

- what am I doing right now that is trying to help there be more of it?

From memory most people don't have answers to them - and that's fine, but it is handy to reflect on them and perhaps work toward finding answers if you don't have them - and the people who do have answers to these questions typically have higher life satisfaction then the people who don't.
