What are some examples of smart contracts that are currently in use on the ETH blockchain, excluding NFT’s?

I have very little actual knowledge of ethereum and smart contracts. When I first heard of ethereum and smart contacts several years ago I had assumed that smart contracts were a feature of the ETH blockchain but that there was very little real world use of them, I understand that this assumption was most likely incorrect however I’m unaware of how smart contracts are actually used currently, NFT’s aside.

Curious to hear how people are actually using smart contacts on the ETH blockchain right now, excluding NFT’s? Are there any high profile companies, institutions, individuals, or governments currently using them? If so how are they being used, for what purpose? Does anyone have any examples of how they use them personally? I’m curious about the real world examples of smart contracts and the utility they provide.
