interesting - for me it has been fast. It certainly could be the type of connection.

you can sign into iCloud directly from your computer via the web.

I may not explain this well.

iCloud Photos is what you describe - automatically. if your phone has storage the photo will be present there and also uploaded to the cloud.

if you have multiple devices you can see all your photos no matter what device and download as needed.

you just need to pay for the storage.

it will put all your photos in iCloud so you may need to do some maintenance. for example I take pics while shopping to see if my kids want something, but those are not keepers so I need to clean those off

You need to look for smells like bad decisions on TikTok.

and make sure there is no acetone in the fabric when you put it in the washer.
