How do I get into my iCloud to view my content

You can sign in here: https://icloud.com

There you can get an overview of your Contacts, Calendar, Notes, Reminders, Photos and Files.

You can also see which devices are connected to your Apple ID.

You can also from your iPhone or iPad go to:

Settings -> Apple ID (Your Name) -> iCloud -> Manage Storage.

There you can see all files and apps that store content in iCloud.

That is correct. A user with an Apple ID that uses iCloud can log into iCloud.com using a web browser on a computer. They can use a PC or a Mac for this.

However, iCloud is not just a sync service. It is possible, without having an Apple device at all, to create an Apple ID, and there after signing in to icloud.com and saving its files in the Files app or in the Photo app, just as if it were Dropbox or Google Drive.

iCloud is a syncing service. If someone created an Apple ID on a PC and was using iCloud, they would still need to have an Apple device in order to use iCloud on a PC.

Set up and use iCloud for Windows - Apple Support

You don’t need to log into iCloud.com to view your iCloud content. iCloud is a syncing service, not off device storage. Therefore, any content that you sync with iCloud is already on your device or accessible in the various apps that you use to sync with iCloud. That includes, notes, reminders, calendar entries, photos (if you use iCloud photos) and apps that work with iCloud Drive.

If OP does not have access to an Apple device, but would like to review its content in iCloud, then icloud.com is the only option.

I am just saying.

Correct. But you can still access content from icloud.com, like on dropbox.com and google drive. Then we can talk about whether it is "only" for sync, I would think it can be used for both. But it also does not matter, just wanted to say it.
