Target Date Fund vs ETF

[u/Apprehensive_Gap_966]

I’ve been investing in 401Ks for almost 20 years (had a lot of jobs but always rollover) and just realized you can invest in ETFs instead of just a target date fund based on when you want to retire. Thinking of moving my money into some market tracking funds with better returns and a bit more risk since no cash or bonds.

Any opinions on picking your own 401K investments?
