$30k. Want to buy some blue chips. What do you recommend?

I’m 21 and would be holding these for a long time. I have already maxed my Roth so…
I was thinking about buying apple, a couple shares of Amazon (pre split) and I’m not too sure what I would choose for the third. Walmart? Disney? Microsoft? Would like to hear your ideas. Was thinking of throwing around $10,000 in each.
