Best SIPs to invest in long term?

Hello, I’m 27 and planning on investing 40k pm into SIPs. I have extremely limited knowledge about mutual funds and investing in general. My investments goals are long term, I don’t plan on touching these SIPs at all. I have separate funds allocated for emergency situations. Keeping that in mind, any guidance about how to spread out my investments into which SIPs would be welcome! :) Thank you.
