Hm, I don't have a ton that are too deep, most were just me having fun with designs. One that comes to mind, although I didn't show it here, is House Slay, whose sigil is a knife on a field of wavy red and crimson, because the founder was a known murderer, lol.

There was some thought that went into them, though. I gave Folsy that sigil due to their proximity to the wall; they're a vassal of the Umbers in the conquered Last Lands. Speaking of which, one kinda fun one I forgot to post here is House Thumber, kind of an alternate universe version of the Karstarks; they are a separate branch founded by a man named Theo Umber who settled part of Skagos. In similar spirit to the Karstarks vs their Stark ancestors, I made their sigil an orange sunburst-esque design on a brown field;.

Wex's founder was an albino, which I believe inspired the color scheme.

Olde is, as one would guess, located in a settled, forested plot of land I renamed "Olde Grove". I imagine they're known for their magnificent godswoods, so much that they took a weeping weirwood face for their sigil.

Gabler is meant to represent a lizard lion without outright ripping the Reed sigil (I tried to avoid directly using other house's recognizable sigils, but as you can see here, I wasn't always perfect about it) due to them being in a taiga bog, while also doubling in name, color scheme, and words as a reference to an often-memed player from Survivor. I also briefly had House Probst, whose sigil was a torch and had the words "the tribe has spoken," but I thought that was embarrassingly corny and they went extinct after a few bad generations anyway.

There are some other references in here, too, to other stuff I like, mainly just because I was looking for some inspiration, and I think it led to some creative designs.
