> Same, I also wish there was a way to just block all calls from numbers not in my address book.
Depending on your phone/dialling app, you can already do this.
For me on a Pixel 3a, using the default Google Dialler I go to the Dialler app (where you dial numbers from), tap the three dots, settings, Blocked Numbers and there's a toggle "Unknown - block calls from unidentified callers".
iPhone has something similar, and I think Samsung's dialler also does too.

> my phone helpfully lists a lot of spam calls as "Scam Likely" but I've yet to figure out how to make it just send those calls straight to voicemail
Similar to my other reply, you may be able to do this with the right phone/dialling app.
Again, for the Pixel 3a with the default Google Dialler: tap the three dots, settings, Caller ID and Spam, and there are three toggles.
See Calller and Spam ID. This shows if a caller is suspected as spam.
Filter spam calls. This rejects calls from suspected spammers (your carrier's normal rejected call handling then applies - i.e if you normally reject a call and it goes to Voicemail, then this is what will happen)
Verified calls. This allows companies which participate in the Verified Caller program to send the business information/reason for calling to your phone when they ring.
