Hiring an independent financial adviser was one of the best decisions I've ever made. It's an occasional check-in to support decisions I make around investments with Vanguard and my 401k. Finding an adviser is the hard part, so it's worth talking to a bunch of people so you can find someone that's comfortable with what you want to do.

I got the Wealthfront pitch when I started with my employer, but I feel much better with my current arrangement. Your comment "I have very little choice but to stay put" is never nice to hear in any context, so I hope you can move along from that place.
