Is PLG right for my SaaS business?

How to figure out if PLG based GTM is right for my SaaS business? Details:- ACV is low - $4K to $10K per year. My product can be used by 1 person teams as well as by 20 person teams. My understanding of my product is that there are a bunch of functionalities that are freely available in the market so we cannot and do not charge for those. But there are a few (2-3) totally unique features for which our clients are willing to shell out the bucks. The free features are cost saving and time saving features. The premium features are revenue increasing features. Right now, our GTM is high touch sales led. We have no self-onboarding and self-serve flows at all. But it is definitely possible to build these flows for the product. Given these details, how do I figure out if a PLG based GTM or even a hybrid PLG + sales GTM makes sense for us?
