iCloud has come some ways but there is still a huge feature disparity between it and competitors like Google.

iCloud is a good accessory if you’re already somewhat involved in Apple’s ecosystem but you have to pay if you want more than a fraction of a thimbleful of storage and it lacks many basic features and compatibilities. iCloud Drive in particular is extremely barebones and completely overshadowed by Google, Proton, and Microsoft.

Also another thing is that cloud suites need to be platform agnostic and iCloud is very ass when used from the web. This will continue to be a major thing holding it back until Apple accepts that iCloud won’t truly succeed until they stop giving an inferior experience to non-Apple devices.
