Do we have a list of bolts that need re-tightening over time that may not be touched during routine maintenance? I’ve heard of people snugging up the valve gaskets bolts and checking the caliper bolts. Are there any other major ones out there?
Loosening bolts over time.

Never heard of that, except if you have wheel spacers which require occasional checks on tightness.
Do not over tight the valve cover bolts as those have a tendency to break off when overtighten. If it is leaking, tighten just by hand 10 mm socket with an extension (NO ratchet).
I learned the hard way, please check your front brake caliper bolts. I used blue loctite when I replaced mine with new (lost one) when caliper came loose.

Did you initially reuse the old caliper bolt before it backed out?
Mine had no history from carfax or in the service records for the caliper bolts. It backed out after an 8hr drive from Las Vegas to Lake Tahoe 4 winters ago. I was lucky there was a hardware nearby where I got temporary bolt then eventually replaced it with oem one when we got home. During the time of the incident when I checked the other 3 bolts, they were all loose.
Another item that get loose is the age old lug nut, key there is just properly torquing it with a torque wrench, I spec it at 105 lbs-ft.

What he said. If they're installed correctly, and not reused, the caliper mounting bolts shouldn't loosen. That's why the install torque is so high.
I have a stack of old ones I use as tooling bolts. I don't drive a Land Cruiser with reused caliper bolts. Ever. But that's just me.

The lower shock bolts will back out if they are re-used without proper threadlocker. If the shocks were replaced, make sure they used a new bolt or threadlocked the old one after cleaning it. Most generic shops will likely just slap that old bolt right back on the car...
i think its a good idea to check the driveshaft nuts / bolts peroidically... especially if you have ever had them apart.
