sites i've seen people used depends a lot and i know insta has't been the best even for some (keyword some) bigger folks due to a lot of the algorithm changes and whatnot so there's all this demand from the site to stay consistently engaged and active (posting near daily, sharing stories and reels, etc)
cursedbeats nails it on the head about luck though because even when using certain tags or keywords you can still get screwed over by whatevers in the code. like on twitter there's whole swaths of words you can't use otherwise the site essentially eats your post, and the same goes for number of hashtags and other little details. it's obviously a pain but i guess one useful thing is that when those kinds of changes happen there's someone who'll share updated tips or threads on what may help
but as for sites other than those you've mentioned the only ones that come to mind are Pillowfort, Sheezy.art, ArtStreet, FurAffinity, Artfol (which is mobile app only afaik), and Mastodon
as for my own links they're here:
