If you stick around the Fed job until you are 62 and have 5 years of service, you’ll have FEHB benefits for life (with the Govt picking up 75% of the cost). Probably the biggest (or only) perk of having a Fed job at this point. Make sure you know the requirements for a federal retirement.
As for the change in asset allocation (shifting to more conservative investments), I doubt you ‘need’ to do anything. You may want to do something, but don’t need to.
There was a recent thread about the value of Financial Advisors recently, in case you missed it. Beware of high fees. Hell, beware of all fees.
