Money market fund vs Blue chips vs all-world ETF

Goal is waiting for a good entry after yet another crash. So as far as I see it, my options are:

• Money fund for around 3% returns (Euro based one, I know the Dollar would be at 4%)
• Buy blue chip stocks (insurances, consumer goods, real estate), either directly for dividends or as CSPs for Theta
• All world ETF

As far as I see it, the money fund is the preferable option if you have no idea what the next market crash might look like. China takes Taiwan, AI bubble, unexpected economy numbers, whatever. If you limit it only to AI, the blue chip option would sound better as returns are higher. Both options make only sense if you assume there will be a crash within a year. If it takes longer, just put money into all-world-ETF and forget about it, as the bottom will be around current levels or higher.

Is that about right? Anything else you can do in times of irrational markets?
