My personal experiences. YMMV.
Instagram has one saving grace: A good population of nutters who stubbornly refuse to follow the changes and still use the tags to discover new art and new artists to follow. You will get followers.
Those followers being able to see your art is another question since Meta is in the business of serving ads to a captive audience and you're there to help them farm data, not share art. If you're not doing that well enough they will choke you out. It's what what they've always done on FaceBook and that makes Instagram unreliable.
I reinstalled Artfol last week. They seem to have gotten most of the technical issues sorted but navigation and finding stuff is still a chore. It reminds me of Discord in that regard. It needs more time in the oven.
Pixiv, DA, ArtStation, Behance, Mastodon, Pillowfort tend to cater to certain styles and genres. All of these platforms do have a variety of styles to look at but it's in the same way McDonalds has more than just burgers and fries.
The future? Continued domination of the internet by a couple of big tech companies and all of the small fry above being eaten up by them at some point. People continuing to say dumb stuff like, "I don't mind because just ignore the ads."
