Which mutual funds to put in new Roth Self Employed 401k?

I currently max out mine and my wife's Roth IRAs. Hers is 100% FCNTX, mine is FXAIX/FTIHX (88%/12%).

I'm just looking for recommendations for which funds to put in the new Roth 401K with Fidelity. I have probably 17 years before retirement, that'll put me at 67.

I was thinking FSELX but probably need to mix in some other stuff. What do you guys think?
