If your 401k offers it you could look into an "equity income" fund. Not for the dividend income per se, but because these a are big stable companies with a track record of paying dividends.

Also, consumer staples are known for holding their ground during downturns.

But the general advice given is to accept that you probably can't beat the market so don't overthink it and just own the whole thing.

Also keep an eye on expense ratios. A lot of 401k providers gouge you on anything but the basic funds. So you'd have to beat the market by that much more.
