Hi Chrisy,
PMP is not the right choice for everyone, but it is suitable for most professionals working in project management.
I can tell that it boosted my Career (and my earnings), and I did and still do benefit a lot from it (meanwhile, I am even a PgMP).
However,
Have you also read the replies to this posting you mentioned?
For instance, mine:

If you are still unsure, I invite you to reach out directly (best on LinkedIn) and we can discuss further to determine if PMP is the best choice for you.
BR,
Markus
