Need advice for choosing fund

Currently investing in the following mutual funds (SIP)

HDFC Flexi cap - 6k
Motilal Oswal Nifty Midcap 150 index - 3.5k
Kotak Nifty Next 50 index - 4k
Bandhan Small cap - 3.5k

I have another 3k left for SIPs,
**Should I invest in Navi Nifty 50 index or another flexi cap such as BOI Flexi Cap?**

Risk appetite: High
Horizon: 10+ yrs
Goal: wealth creation

I have 5L in emergency funds. Just looking to park my money monthly in investments for the long term. My target is to accumulate as much as possible for the next 10 yrs. Don’t want to redeem anything atleast for the next 10 yrs, or even more.
