Yeah lead free solder is perfectly fine.
Where I live, lead solder is even illegal to sell and buy unless you have a permit which is impossible to get for individuals

For systems that...may experience some degree of vacuum...it's common to use lead solder still because it doesn't tin whisker so unfortunately it's still around for some of the stuff I've worked on.
