Rescue large amounts of important data from old junk phones?

I have a defective Samsung Galaxy S10. Half the screen was black, so I lost it accordingly.

By chance I started it after a long time and it works again, except for the defective USB.

I.e. But, I have no connection from the laptop to the mobile phone. Strangely enough, Bluetooth also failed and is also not the right one for the amount of data.

Question: How can I comfortably copy> 20GB data from one device to another? Think of online cloud (only free of charge), a good app or a home network…

A couple of google drive accounts. I think you have 15GB per account

will be a task.
