Cause eventually you will run out of 4TB. (aka the max storage an Apple ID can own) Do I have the chance to upgrade to a bigger iCloud storage? Or do I have no chance other than having to switch to Android or something.
iPhone SE, iOS 14
No it technically isn’t. I heard that if you have the Apple One plan you can get your storage up to 4TB. https://9to5mac.com/2020/10/30/apple-icloud-4-tb-storage/amp/
I stand corrected. This article What happens to your iCloud storage plan when you sign up for Apple One - Apple Support and this one Upgrade your iCloud storage plan - Apple Support now do include mention of 4 GB with Apple One, but not higher.
Even if you switched to Android, as long as you want to keep more than 4TB of data in the cloud, you’d need to find a cloud service that offers a storage plan with more than 4TB of storage. Apple currently does not offer anything over 4TB. Google One only offers up to 2TB storage.
2 TB is the current maximum.

Depending upon how you use your storage you could investigate other storage sites for things which do not need full syncing capability within the Apple environment.
