Yep, that's one option.
The other is to get involved in the community goals (CGs) which are updated every Thurs, typically with a new bunch of 1 week location activities. From what I've seen, should be fairly easy to make a few million without a massive level of effort.
You do forget that many community goals cannot be done by a new player?
Not in the starter ship at least, let alone the need to outfit it, find a way to the stations involved, because they are too far away from the "outer rim".
And the drive is too small to get to more than 5ly away.
