The lenses are sapphire coated and pretty difficult to scratch. I wipe mine with a the tail of my cotton T-Short all of the time and it's fine. You're not going to scratch it so I wouldn't worry about it. That being said it doesn't hurt to get an inexpensive micro fiber cloth or even some inexpensive lense wipes for occasional cleaning. The front screen is softer glass and will pick up small scratches so use a screen protector or at least lenses cleaning wipes or microfiber.

That's not a moon.
That's a space station.
Nope. I don't sleep with it on. Sometimes I don't even wear it on weekends or vacation.
No. It's just convenient access to information without pulling one the phone.
Verizon's call filter blocks anything that is suspected spam (if you set it so.) There is also a setting "Silence junk callers" that specifically silences "spam likely" (even without call filter.) I very rarely get a call that rings through. Check to see if your carrier has a spam blocking app.
Almost every Apple product I've ever bought was repaired or replaced under warranty the first year. Oddly my latest purchases have not so far. The 14 Pro is going on year 2 OK my several years old iPad Air 4 is still fine and so is my watch Ultra so far.
Different default ringtone for callers not in your contacts.
Block or silence calls based on wildcards or number ranges (like an entire area code.)
Block/silence calls with no caller ID.
"Silence unknown callers" is too blunt of a solutions. OOMA has all of these options and it's handy.
If not free storage, at least make the backup free. They can still charge for photos and other storage. Just make the backup not count so that everyone will use it.
Nobody ever mentions this but FireFox focus has a safari extension for ad blocking. It's really quite good and almost never beaks a page like some of the others I have used. Very low key and just usually works and is free.
Most stolen phones end up in Shenzen China and stripped for parts or in the hands of a scammer that will try to trick the original owner into unlocking the phone via blackmail, threats, or phishing. Others wait to see your passcode then steal them so they can hijack your iCloud account. There was a short documentary on where the phones go. I don't recall where so saw it.
