I think Cthulhu mythos is more fun with less straight up "gods"
Cthulhu is a possible alien giant wizard from an earlier version of the universe or another one. , Or its a "big brother" type fake person by an entire race of bengs that made up a singular "leading figure" for humans and other cultists to more easily rally around. Honestly perhaps more impressive than a "god".
Chaugnar Faugn is a feeding appendage of something vaster that has possibly gotten too independent . A rogue "hand of god" that might eventually cause problems for the collective
Glaaki: A giant sluglike thing in a British lake that's spines turn people into undead slaves it then forces to inscribe information and create tomes including the The Revelations of Glaaki collection. Was the meteor it came in a crashed spaceship? Is it some malfunctioning piece of technology doing its job of recording and collecting information using humans as a replacement of the crew and lost other "machines"? Possible "Roadside Picnic" type of thing ?
Y'golonac is imprisoned somewhere and sometimes managed to possess people (which affects bodies) and form a composite entity of both minds. Seems has in past it or someone managed to spread fake extra volume of The Revelations of Glaaki that allows it to possess readers, and seems hosts maybe able to transform others like a vampire... . Might only be a "god of depravity" due to being insane from imprisonment and overwhelmed by physical sensation. Or they are the eldritch equivalent of a gross pervert on internet who is in it for shock value. Should be noted the host that started a cult was a small business owner. Would all hosts do the same or did some megalomania of the human host seep in?
Vulthoom: a charlatan ala Wizard of Oz with alien technology, and if Glaaki's tomes are to be believed is a child!
Hastur....well possibly but a lot of thing are named "Hastur" so you gotta be specific. And they and King and Yellow might not even be connected.
The Dweller in The Gulf: a slavetaking monster, link has a great take.
The Crawling Chaos: a 'messenger of gods": perhaps might just be a soul who's all shared bodies and incarnation across time and space are self aware of place of universe. It is many things and many creatures across time and space and some of those things can take over bodies, or make copies of self in other ways. Randolph Carter's tricks to the extreme?
Tsathoggua: claimed to be a god but uh... well seems to mostly be exchanging knowledge to sorcerers in exchange for not having to get up to get its own meals. Luckily Earth life is not its favorite, but hilariously you'll want to summon something tastier than you when going to meet them.
And the closest things to Western culture idea of gods...most uh seem imprisoned by bigger fish or even afraid of mortals...
