+1 to focus mode; at least on Samsung-flavored Android, you can set a recurring schedule so that focus mode (or any mode) automatically kicks in on certain days/times, which I use to block notifications from and access to certain apps during peak working hours.
Another feature I really like that also might be unique to Samsung-flavored Android--it's been a decade since I've had a device running Vanilla android, lol--is the overall daily screentime tracker. It's purely observational, so there's no penalty for going over, but unlike the app time limits that you can snooze there isn't a way to subtract time that you actually spent, which helps keep me accountable. Mainly I like having a widget that tracks the day's stats on my home screen, because being able to go "oof, did I really spend 45 minutes on <app> today already?" is a strong motivator for me to shape up.
As a bonus, you can also _exclude_ certain apps from the time limit tracker, which I like because it nudges me towards more constructive habits. Stuff like my notes app and Waze don't count towards the timer, nor does my e-reader of choice, which means I'm more likely to read a few pages of a book if I have time to kill since it's "free" against my daily screen goal.
