How to manage portfolio allocation after achieving FIRE?

There's plenty of info of how to achieve FIRE. But after achieving or exceeding your FIRE target and actually living the FIRE lifestyle, how are your financials supposed to be invested?

The common pre-FIRE strategy is to invest disposable income in high growth potential instruments such as stocks, ETFs, etc. The overall portfolio will be tilted towards capturing growth with a small percentage, say 10 - 20%, catered to bonds and emergency funds. This will continue till FIRE amount is reached.

However, once FIRE is hit, what happens to the portfolio then? Do you continue with pre-FIRE portfolio allocation? Such a portfolio is not geared for regular withdrawals and downside risks are high. Transitioning to a lower risk portfolio with lesser exposure to growth seems to be the answer but what kind of approaches are available locally? SRS/CPF is disregarded here as this is supposed to be before any of their age requirements.
1. Stick with current portfolio but adjust allocation to 40% equities 60% bonds. Monthly regular withdrawals support post FIRE. Can treat this as monthly re-balancing.
2. Switch to 80% income generating portfolio, such as dividend or REITs based, 20% growth.
3. Buy retirement plan or annuity, supplemented by point 1 or 2.
4. Others?

Curious to hear from those who have FIRED.
