iCloud Photos not syncing or stuck

Hi friends, I entered the apple ecosystem last month and just bought the iCloud+ service.

I have a lot of pictures and videos on my phone, some are in RAW mode using the 14pro, others are live etc... More precisely, there are 754 pictures and 167 videos in total.

I started the photos sync yesterday, and since I woke up like 5 hours ago, the syncing is kinda stuck.

The following image shows the total of files in my phone:

And since I woke up, it is still showing that 375 files are still being synced to iCloud, although in the next picture you can see that all of them are in the "in iCloud" field:

In total, these files were more than 60gb in storage size, and you can see that it is only 23gb in iCloud, while stating that all of them are already in the cloud.

Now, in the next picture you can see that there is only 9gb of photo files in my phone:

Isn't it weird? Because it was 60gb, and in iCloud there are only 23gb while there are 9gb in my phone... something doesn't seem right.

And last but not least, today morning all those 60gb were being accounted in my local iphone storage instead of only 9gb, and then I restarted the phone. After that, the photo files storage was 9gb and there was 40gb of "System Data". Now there are only 14gb, look at this:

What am I missing here? Did I do something wrong? What should I do to finally have every photo and video synced to icloud?
