Notes
Notes on my phone sometimes migrate to my email. How can I stop that? I'd like to keep the stuff in notes/" I've never experienced this issue. Are you using Gmail by chance? Or another email service. Read about organizing Notes in the online guide. I wonder if you have multiple "accounts" where Notes are enabled in Settings > Notes > Accounts ... If so, you can move individual notes from one account to your iCloud designated account (then turn off the other accounts in Settings . Notes > Accounts).

Email
Be kind to others when sending several photos by sending photos at a reduced size. This is obvious on iPhone as there is a prompt before the mail message is sent. On the iPad there is a HIDDEN button! Experiment by creating a new mail message and add three photos. On the Cc/Bcc, From line you will see "Images: 50 KB" - this is the hidden button. Tap the word Images to expand all the fields and show the Image Size options: Small, Medium, Large and Actual Size. Each size option is shown with the amount of storage/data required to send the photos. Small is recommended. If the recipient wants to print a larger version of the photo, send just one photo per message and set the size to Large or Actual Size. This is not a feature mentioned in the online user guide!

If your Notes, Mail and Photos are NOT available to all your devices, make sure all devices are logged in to the same Apple ID account in the Settings app.
Photos can take up lots of room in your iCloud and on your device. Consider turning on Optimized Storage. Open the Settings > Apple ID > iCloud > Photos > Optimize iPad Storage. Same for iPhone. Subscription to iCloud+ includes documents, videos and photos - on my 200GB subscription ($3/mo) easily allows me to have 21,800 photos using 130GB with room for other documents and more.
Sending Photos to iCloud will be automatic if your enable it - Settings > Apple ID > iCloud > Photos > iCloud Photos > ON.
