1 and 2 should be daily/biweekly/weekly check-ins either via a stand up or by a message/email, they do not warrant a 1-on-1 and wastes people's time to make managers feel better.
3 seems like it could be abused by a manager and feels a little forced by the sounds of it. Does the manager share equally about their availability to act accordingly?
Think of it more like "oh yeah my kid just started soccer at school", "we found this neat new restaurant", etc. It's relationship building. Work is more fun when you like the people you work with!
Some people communicate or receive feedback better in person/video than over email, and that's okay!
I've enjoyed sharing some war stories in my experience volunteering at various places.
I'll totally talk for hours about any number of topics.
I've also done what's probably "life coaching". There are a lot of things I've learned managing a mental illness. Not a therapist, but I know a lot of the techniques and what's worked for me or other people.
Be careful about playing work therapist, it can lead to boundaries getting blurred in a way that becomes detrimental to the relationship and ultimately your career over the long run.
If someone really needs help, the most I'll do is spend 15 minutes showing them how to find a suitable professional.
It's really stressful trying to prod someone to get their life back together when they clearly need professional help and maybe medication.
I'm an engineer, I'm not built to be a life coach in any way.
Only close friends get my time and energy. (Coworkers are not friends.) Even then, I've got firm boundaries. I'll be there when I can but I'm nobody's emotional support dog. :)
