I will tell you, anytime I start a new WP website be it a blog, webstore, etc. I always do the boosting packages. I only use them the first few months. It has been awhile since I have done this, maybe the last time was 2019? So I am not sure if it helps or hinders a site these days but I know when I did it, it always helped boost traffic and rank my better on Google - At least in the early days. You have to put in the work to keep the growth going or it just disappears.
