Great list Ben, and all from experience too. I’m finding Microsoft Teams is a real challenger to Slack right now (we’ve just moved across). I’d also throw in Smartsheet which is pretty flexible for managing projects (we’re also creating Registers in it). Also Clockify is our new toy for tracking time spent on projects — can’t believe it’s free. Timetastic is a great, low-cost way to track who is in, make leave requests etc
