If the OP is looking for investment education, she and her DH should attend basic investing seminars at the local Fidelity and/or Charles Schwab offices. Edward Jones makes money by selling high commission, high expense ratio mutual funds and other financial "products" to individuals with no investment knowledge. There is an Edward Jones office on every corner in Sun City in Arizona, fleecing the senior citizens that don't know any better.
Stable value funds have their place. I have money in a stable value account in a 457 plan. I moved the invested funds to an IRA a few days after I retired, but the 3 percent plus yield on one year's worth of retirement expenses was better than any bank and there were none of the bond fund risks. As much as I hate Prudential for their 457 mutual fund offerings, I am happy with the stable value fund.
The OP and other folks in her position should understand there is no substitute for education when it comes to your money. No one cares about your money as much as you do, and there are plenty of people out there that will try to convince you they can do a better job managing it than you can, because they are "professionals." With a little education, you can overcome your fears and do a better job yourself.
