Starting with personal investments

I have been out of touch with the market for few years and not really sure where to begin from. I have been hearing about a recession coming soon and in general market taking a dip. However, I don’t want to delay investing further as I am still a fresher and want to get in early. My plan now is to invest about 50k or 75k in some MFs as a lumpsum amount and start two three SIP of about 5k each in various sectors. My thinking: For lump sum: Due to recession news, safer bet would be to put half in Large cap, 25% in some form of commodities while rest 25% in upcoming Indian sectors like green energy etc. For SIP: Two or three SIP 5k each, one in small and mid cap but other two I have yet to think about. What advice would you give for someone who wants a diversified portfolio for long term but also might need to withdraw 20% in next 5 years to partially fuel upcoming personal expenses(car, marriage, home,etc). PS: monthly salary: around 1.1 lakh(after deductions)
