Investing entire PF fund

I am 35 years old male. I worked for 10 years and accumulated 49 lakhs in epf alone. I have not been employed for around a year now as I joined my ancestral business. I am already invested >95% in real estate so don't want to divert these funds there. Other than real estate I have nsc worth ~21-22 lakhs and NPS around 16 lakh. I am looking for a long term investment. I am thinking of one of the following:

• lumpsum investment to diverse MFs now
• STP to MFs, start now
• let the funds stay in PF for next 2 years as they pay you interest for 3 years after you stop contributing. And then do one of the above.

I would like to know from you, what is it that you recommend and why. Also if we are talking about diverse MFs what is good diversification. For instance this is what chatgpt suggested when I asked to diversify 50L funds in mf Large Cap / Flexi Cap Equity 30% 15,00,000 Mid & Small Cap Equity 20% 10,00,000 Index / Passive (Nifty 50 / Nifty Next 50) 15% 7,50,000 Debt / Corporate Bond / Banking PSU Debt 15% 7,50,000 Hybrid / Balanced Advantage 10% 5,00,000 Gold (ETF or Fund-of-Fund) 5% 2,50,000 International Equity (US or Global) 5% 2,50,000
