I remember using Lotus Organizer for this until I switched over to macOS a few years ago. I still haven't found a good alternative that combines it all in one place and is as lightweight. It had all those goodies like automatically moving undone ToDo's to the next day, a lot of options for reminders/due dates, schedule conflict checker etc.
Notion is great, but I too find the extra work distracting and unnecessary.
