I had reasonable success deleting Safari from my iPhone. I still need to hit weblinks sometimes, but iOS does a reasonable job at providing a basic web browser for those (no URL bar so I can't then waste time on it).
Of apps, I am currently using ScreenZen, which links into ScreenTime to provide a warning message and delay before I browse a customisable list of websites/apps. (HN is on it...) It seems to work better than OneSec, though it isn't perfect.
[update] Another thing I find useful is to regularly measure my screen time, and have a manageable goal for how long I spend. That's more productive than hoping to go "off-grid" forever.
