I'm going to lean in the opposite direction of your question.
... a remote (online) poetry writing community, ... that produces growth within your personal creative process ...
I see 2 separate desires which are somewhat in opposition: a community, and personal growth.
Community is external, so you won't have much control over the quality of the group or it's ability to appreciate or encourage you. Communities are funny things. As social animals we need to reach out to others. Unfortunately that is not always the best thing for an artist/writer's personal growth. Being in a group tends to create a dynamic where most people within the group act the same and agree, just for the sake of being part of the group. Even here on WritingSE, it's both fun and a distraction that your participation is "scored" by the website. It is what it is, but participating here is not writing our own works. Most of us probably use it as an antidote to burn out, writer's block, boredom, and loneliness – also the desire to participate in making the world (the world of a few other writers) a better place.
Now about your personal growth as a writer. This is, frankly, more directly important to your craft. You must write to get better at writing. You must curate your own writing, edit and re-write your own works, and experiment in how they are published. That probably means a website (wordpress.com is free, but there are others). Most of all, you must write for yourself, without input or approval from others. You must find your own unique voice, and discover how to communicate a range of ideas and emotions through that one and only voice that you have. You must chart your own course into the unknown. The best a community can offer is a generic way to make your writing more conformist, to "normalize" you through the law of averages. This is not growth, and it is not personal.
It is a catch-22. You need both, but I am suggesting one is far more important to you as an artist. One is your pure creation, it is the only path to personal growth. Community can be good too, it will fulfill other needs, but rarely will it lead to personal growth. Even if you find a good community, you should not "put all the eggs in that one basket".
Have you ever heard the old saying that if you want to find a relationship you should just work on making yourself happy and the relationship will find you? Yeah, that's not quite my advice, but there is something constructive in that idea: prioritize your personal growth – it's the one that is under your control, and it's not subject to the approval of strangers. Don't put too much of yourself into a community. To be honest, you will need that community (or several) to take a break from your personal growth, to share and communicate in the community without expectations that it will serve your art, because it probably won't. Communities and friendships can be a source of inspiration and learning – even healing – the best way to learn is to help others work through problems that are not personal to you. But communities can go the other way too, they can be petty and conformist, with arbitrary rules that favor the favorites, and that can be a bitter pill if you are a person who communicates a little differently, or you are too generous with your time and attention. Communities can become habit, a place we go to ignore our work and problems (and feel we are still achieving a writing goal, even if it isn't our writing goal.
TL;DR – there may or may not be a perfect community out there that suits your needs, if only for a short while. But you'll still need to work on your personal curated space where you can present ideas and words and pictures exclusively to please your own sensibilities. This personal growth space will need every bit as much of attention and goodwill that you would bring to a community, with the added benefit that you set the standards and you are the only ego that needs to be served. Your personal space will need to be secure, before you can honestly give and take from a community without it warping you into their version of what you should be writing.
