I have been using both types as well

On the paper side I have made my own templates (one week on A5 sheet), and also use the backside of used paper. After retirement and my oldest daughter graduation a few years back, I got a ton of paper to utilize. Most of them are used for TO DO lists for short term task planning.

On the electronic side, I use an App on the phone for medium term and use MS Word for longer term planning, and MS Excel for budget calculations
