Out of all your list I've only watched Get Out and Colour Out Of Space. And, well, A Quiet Place, but I wish I didn't. The whole premise is so dumb, ugh. But whatever.
Anyway, here's what I have for your grotesque and macabre, no jumpscares stuff.
David Cronenberg
His works are crazy. Barely can be called horror, but those designs, man, those designs! If you haven't tried it, just look through his filmography on wiki and pick something for your tastes. I haven't watched his full filmography yet, but every movie I've watched so far were top-of-the-line body horror, even if the movies hasn't been labeled as horror.
Also, most of his famous movies are completely surreal by the end of them, and I do not know about you, but I could barely understand what's going on and what is the point of it all. Pretty much the only one that gave you a direct answer to a pretty obvious idea was eXistenZ. And, well, Scanners, but Scanners in general is kind of... shallow in terms of a plotline. Scanners is more like an action movie with... kind of a magic in urban setting. Next to none of the body horror as well. I've still enjoyed it a lot though.
Brandon Cronenberg
I've watched two movies out of the three he has at the moment, and, IMO. so far he is definitely his father's son. I mean, I don't know, maybe it's not everyman's horror, but for me simply the world that Brandon manages to show is quite unnerving. Like, the world in Virus where people actually pay for infecting themselves with viruses that pop-stars and media icons are infected with. Among other things. There are also people eating pop-stars' cloned meat, corporations who control it all by making viruses inert, et cetera... That was one of a hellscape in my eyes.
The Thing
Carpenter's masterpiece, just needed to be here in case you haven't watched it somehow. Top of the line body horror. The second Thing that was not made by Carpenter - I've actually quite enjoyed it as well, despite all the letdowns and the fact that the publisher, for whatever reason, decided to switch from animatronics to SFX after animatronics were complete. Still, 2011's movie is also quite enjoyable, or so I think.
Society
You want grotesque and macabre - this is the piece you want. Pretty much unique movie from 1989, all but forgotten - or so it seems - but oh so good. Haven't looked at the other works from this director yet, but they say the first Reanimator is good (and much more famous).
And, I'm not sure how grotesque they are, but... maybe The Void, The Whisperer In Darkness and Glorious from my first post would be the pieces you should take a look at as well. Unfortunately, Cronenbergs are quite unique in their style, and there are few things that rival them. But I hope the list above will be able to set you up with a good movie for quite a while.
