^ GoodReads can be pretty helpful in finding you reccomendations based on the stuff you already read and like, if it still has that function. Googling stuff like "books about [blank]" can be alright, or if there's a book you really love and want more stuff similar to you can try "books similar to ___".
I've seen a few book club groups on Discord about, you could try finding or making one, that way you'd have peeps to talk about the books you read with, too, if that's a thing you're into, and they'd probably have recommendations for what to read next.
There are also various sites where you can put in authors or books you like and they'll give you recommendations, or AI for that function which may or may not be helpful. The site What Should I Read Next? has a similar function and I'm sure you could find others. As some others said, too, you could always just keep an eye out for interesting covers; I've bought a few books this way!
