Strange Aeons is a Mythos-adjacent psychological horror Adventure Path, but while Call of Cthulhu is its spiritual cousin, it remains a Pathfinder campaign. Your characters will grow in power, and ultimately, be able to face the threats that exist (compared to CoC, where you just go insane and die). Aeons has a lot of what might be called ‘bad vibes’, and experiencing those bad vibes (and getting through / over them) is a large portion of what the Adventure Path is.
