Now I have similar system in place, however I kept the Chrome installed because of the bank authentications just like you said. But I'm using the Wellbeing app (Pixel) to block all the social media domains so even if out of habit I start typing twitter, it does not load.
The daily game I play is rotaboxes that's super relaxing and exactly, has an end.
I really enjoy reading someone else who is going through the same struggles overcomes them. Good luck sticking to them.
