I think my r7000 is dying after 4yrs of use, now frequently dropping wifi connections

[prexactly]

After 4yrs for good use and functionality, my r7000 is now frequently dropping wifi connections and making high pitched noises (intermittently).

Now attempting a default factory restore (and maybe a firmware downgrade?) to see if that helps, otherwise looks like it might be time for a replacement.

Any advice and/or recommendations?

You did not indicate firmware version. I am guessing latest, 10.0.9.64. This version has issues.

Would suggest you back rev to 10.0.9.42.

Yep, was at latest (1.0.9.64).  I'll give 1.0.9.42 a try.  Thanks!
