One very important consideration when setting up your account: photos and such can only be tagged with your name if your name is registered with the site. So for example, one of my daughters has had a FB account since her early teens, which as you’ve noted is necessary – in her case, quite a lot of official college stuff works through FB now, which I find weird – but because her account is under a pseudonym her actual name is not attached to anything on the site.
If you have to use your legal name on the account for work reasons, use some variant that isn’t as identifiable. Your first initial only plus your surname, for example.
