Simple spreadsheet + calendar Website + app easy to learn with these inclusions:

I am looking for an easy to use app plus website for personal organization that includes • Spreadsheets / Doc creation (like Smartsheet) • Doc uploading • Calendar • To do list with the capability to add tasks to the calendar • Homepage that shows all the categories at once (like Basecamp) •Ability to put notes on EVERYTHING because I forget things •Simple (Notion is overwhelming and messy to me) •Safe for some personal information like medical records and follow up questions. (2FA) •Plenty of storage for free (or until I get comfortable and decide to upgrade). •All in one (not Microsoft Suite, Google products, etc.)
