How can you track this down? There is no way to even know if your email made it to a person's inbox (like a kind of forced "received receipt" -- I don't care if they read it yet).

This is easily explained if you were hosting your own Postfix or something. There are a significant number of hoops that legitimate email senders must jump through in order to ensure their email goes through properly. DKIM signing, SPF records, rDNS, etc. These are some of the ways for gmail and apple identify you as a legit sender as opposed to a spammer.

In general, ISPs won't want to let spammers know they're are bulking email. That's why you aren't told.
It makes sense that they wouldn't notify you if they tanked your email because they think it's "super spam" or something. It is frustrating though. Especially since I'm talking about very low volume emails (not a newsletter or anything). Do you know why some emails are silently dropped while others are marked as junk and allowed to pass through?
Yes, definitely... at least for commercial sending. SendGrid, SES, Mailgun, Mailchimp - there are a lot of solutions for outbound commercial / bulk and they're reasonably priced and easy to use. They take care of all of the nuts and bolts.
For personal email, I started seeing this change a long time ago and stopped hosting my own at least ten years ago (around the time 1/2 of my DSL got consumed by spam bandwidth). At this juncture, I keep all of my domains on Gmail.

Probably depends on spam score as to whether it gets bulk foldered or killed immediately, and the ISP.
