Welcome to the club! You’ll never swap back. There’s a lot of good info here already so I won’t repeat a bunch of stuff.
The brushes with a nice block of lotioned cream are best but can cream still works fine. I got a $30 screw top razor and can get very close. I go with the grain then reapply cream and go against. One thing to be extremely careful of is never slide it sideways ha. It’s a blade.
Likely the first time you use it you’ll lop off any imperfections in your skin. Those generally grow back flat. I shave my head with one and the first couple shaves when I switch styles are a bloodbath lol
