I live in Australia, so YMMV, but for me, the things I needed to update were:
Government/their services and programs, local and federal
Medical things (insurance, doctors, etc)
Banks/Financial Institutions (I don’t know how a 401k works, but that probably is included)
Insurance
Car registration
Identity documents
Wills, if you have one
Company registrations, if you have one
Beyond that legal obligation, there is no one you have to tell if you don’t feel comfortable. I took the opportunity of legally changing my name to finally come out in the rest of my life (work and uni), but you don’t have to.
Also fun fact I can tell that Medicare (Australias one) definitely doesn’t distinguish between trans and cis women because the week after I changed my name/gender I received a letter telling my I was due to get my cervix checked lol
