If it's between analysis paralysis and target funds, just pick the target funds. You will likely still do way better in the end than just sitting on your cash. For my friends who are not focused on FIRE (almost all of them), who are scared to invest, I would probably recommend one of these in a heartbeat. If the simplicity of target funds gets them to begin investing now (20s), then that would be awesome.
I have moved all my funds out of target funds, though, because I'm planning for early financial independence, and really don't want anything to do with a higher bond allocation. I'm in the accumulation phase, so risk is more desirable for me right now.
It's not all about returns, though, it's also about knowing yourself, and if you know that market fluctuation will freak you out, then you may just have to set some new expectations for timing your path to FIRE, and that is OK. And honestly, when most actively managed funds charge 0.50% and higher in fees, who freaking cares about the difference between 0.04% and 0.14%? Ok, a bunch of mustachians, but do you get what I'm saying? 0.14% is still way ahead of the game on expense ratio :)
