Not sure if best, but:

• cleaning the kitchen in the evening. I listen to podcasts or music while doing it, and the mornings are easier as I don’t have to confront mountains of dirty dishes.
• reading - I try to dedicate at least one hour a day and read a book. I guess with general decline of the content on the Internet it got much easier to go offline.
• meditation and relaxation techniques - I started doing this as a teenager and thanks to hours I’ve put in I have no problems falling asleep. Even when I am high on caffeine I can relax my body during the night and wake in the morning not feeling like a zombie.

I have Dynalink DL-WRX36, running openwrt since day 0. Iirc it was 60 euro year ago. Everything works, wireguard too. No complaints. I believe there is openwrt stable build for it already, though I an still running snapshot as I am too lazy to update.

They collect minor things like search terms and app usage info. The rest is stored on the server only if you explicitly upload a photo or a recorded track or something similar. No collection of location data or WiFi networks etc. The telemetry can be blocked of course if you have such setup (VPN+pihole for example)

Mapy.cz are the best maps available on desktop and android. They use OSM as a source. There is some tracking but in this case it’s worth the hassle.

Stop obsessing about Reddit and create a content on Lemmy instead. People will come once they see there’s enough activity here.
