If your most important of important files don't exceed 2GB then a Dropbox free account is a no-brainer.
If you have important files that are roughly ~100GB, Google Drive is only EUR 20 per year to upgrade from their 15Gb free tier to their 100GB offering. Again, a no-brainer.
If you're concerned about the privacy of your files on cloud services, then use Cryptomator[0].
Cryptomator is for more advanced users and you need to read the DOCs before using it. Personally though, I found the interface intuitive and I don't consider myself that smart (depending on your definition of that term).
