Hey! I can totally relate to what you feel and I think that's common to all of us minnows (even planktons and dolphins in some cases) who are just trying to find our feet on this platform. I feel with every passing day, there is so much content being produced on Steemit that it practically gets really difficult to read and engage with everyone, even if you are following them. But you have to keep at it. Persistence is the key here, as has been said by many more people other than me. I'd say don't get bogged down and keep writing on topics that come naturally to you. That is the only way I feel one can ensure quality and consistency. There are so many people on this platform and I'm sure what you write will be of interest to someone. Good and useful content is a very subjective thing. It's just a matter of people's interests. So no, you don't need to write "fluff" just to be read.
As far as creating a FB page is concerned, in my opinion, I'm not sure how much that would help. Fb has just become junk now. I fear that page might just become one of the many pages people like or follow but never actually bother to check. I can say this from experience because I follow many pages and also manage a page for my own website. The engagement there is really superficial.
I like the idea of Discord channels more because it's a small community there and there are more chances of being noticed and forming a real connection. It's just a matter of spending time. Plus, it's more interest focused. For instance, I'm interested in Travel so I've found great Discord groups for that. As the platform grows, there will be more such groups coming up. Maybe you can form one!

I have upvoted your post but well, my upvote doesn't count anything in terms of $. Sorry for that! :)
