Wow, that's quite an impressive number of offline activities.
Right now, I spend more time using tech than I'm comfortable with. I started living nomadically out of a backpack 6 months ago so the need for physical minimalism meant that I went back to tech for some activities, like taking notes and planning my day. Subscribing to a newspaper or magazine isn't an option for me right now, and with the pandemic I've not felt able to avoid the news altogether so I get it online.
For writing I use a minimalist word processor, FocusWriter.
You ask for additional advice. Are there any particular areas where you feel you are using tech too much for your health? It sounds like you have your tech usage under control, so maybe you don't need to push this philosophy to extremes.
