iCloud drive keeps filling up storage

Recently my phone started running out of storage, every single day. I deleted all the photos, I had thousands, yet after a couple of days, the same issue cropped up again. The phone was full and I did not install anything and neither did I take any photos. I soon discovered that the issue is iCloud drive, it keeps filling up whatever space it finds. Of course, my iCloud drive is synced with my Mac and it has become an indispensable tool for my work. I have 2TB capacity on iCloud, of which 64GB are being used, with stuff on my Mac. Unfortunately, my iPhone only has 32GB of storage space and iCloud drive wants to somehow put those 64GB on my phone. I confirmed this since when I switched off the iCloud Drive from the settings, the storage issue disappeared and I had more than 6GB of storage available on my phone. I had had a similar issue with Photos, I used to have a higher capacity iPhone and the photos did not fit on the new lower capacity one. So I had to delete photos from the cloud as iCloud kept downloading them to the phone. I had to stop using photo syncing and started using a third-party solution. iCloud is an amazing feature but it does not make sense to fit all the data on the cloud onto all the devices. I have huge files on my Mac but never use them on the phone. Can't apple's developers set a limit on how much of the data available on the cloud, is downloaded to each device according to Its capacity?
