try this one https://onyx.run/.
Block time 5sec, rewards 2 ONX for each block, halving time ~10years

take a look at this pool (ordering by ALGO) https://pool.rplant.xyz/ it lists some CPU-only coins.
A good practice for discovering new coins is starting by the hashing algorithm. For CPU-only coins you can look at scrypt family. Yescrypt and specially yespower (yescrypt variant) are minable on CPU, GPU-resistant and ASIC-neutral (that is ASIC maybe better than CPU but not in orders of magnitude like sha256).

CPU-only coins can be used even for monetizing services like websites or mobile apps. If you are a web developer for example this module can help you monetizing websites by using the end-user's cpu power https://www.npmjs.com/package/@marco_ciaramella/yespower-web
