Best places for Cloud Storage?

I’ve been doing a lot of 3D work and game modding on my computer for the last few years and I want to make sure that I have reliable backups of my work online somewhere in case my computer dies. Of course, I do have some physical backups as well, but I feel like I’d feel the most safe about everything if I had both a physical backup as well as a backup on the cloud. I just know I’d be devastated if anything happened to the stuff I’m working on and I want to make sure that everything is as safe as possible

Are there any places you would recommend? Especially since a lot of the cloud storage services I'm finding seem to be pretty expensive
