I love Multiple Inbox for work emails, although for home I don't. My work email tends to get a bit cluttered during a project, but I try to get back to Inbox 0 when I get a moment to go through things.
My Multiple Inboxes are: Unread Inbox, Starred, Action/WaitingOn labels, Drafts and Unread (non-inbox). I had to add the last one as I was missing emails I hadn't read but had setup filters for. This deprioritizes them, but I still see them, and I can easily just mark them as read as they generally don't require much attention.
The other tip I'd say is learning the basics of keyboard shortcuts - I can open, assess and archive/delete an email very quickly because I use e/# (archive/delete respectively). I can burn through the unimportant emails very quickly that way.
