What are some good strategies to help set my children up for financial success?

In addition to 529 plans, I have opened custodial brokerage accounts for my kids. I told them that for every dollar they put into the brokerage account, I will match it with a dollar. For every dollar they withdraw, they need to replenish before my 'corporate/household' match resumes. This is to motivate them to "let the money grow".

They each have a crypto wallet with a small amount of BTC/ETH.

What are some other things I can do for them today to get them excited about building/working to financial independence?
