Well, yea. You're a manager :)
> Which meetings would you cut?
Well, 30 min standups seem long for what I assume are two groups of 4 people. I'd probably shave off 5 minutes from those every so often until you get it to 15 minutes each. That will net you 2.5 hours a week.
pro-bono project during business hours: sounds silly if you're feeling stressed about time management.
"50 days of learning": continual learning is good idea, but I save this for after work hours, and probably you need to do the same. Especially since you're already doing multiple training sessions a week during the work day.
Going-away get together for team #2 member / virtual happy hour: shouldn't these be happening during "after work" hours?
Finally, 9-5 is banker's hours. A typical 40 hour work week would involve working from 8-12pm, an hour break for lunch, and then from 1pm-5p. If the daily operational review meeting is running from 7:30am-9am you're doing it wrong. It reads like you want credit for attending an early meeting but aren't accounting for the 8am-9am hour?
