I suppose a small meteor could cause a boom.

Thank you again Pete. Something on your list could very well be what we’ve had here. I don’t think it’s the sonic booms because there was at least enough ground shake in the biggest boom to knock off a neighbor’s shed door. Yes, it was rickety, but had 2 hinges and functioned enough to close and lock.
Smaller booms have reminded me of long thunder tho, under clear skies. I started watching the second hand on one as I was cooking and using the timer. The “thunder” rumbled over a minute and a half. Not a cloud for miles.
Thank you for feedback. I’m sure I’ve slid too far. Sorta glad to know it’s not just here. Like any good human I’d love to figure out what it is. From the links I see we have company in that puzzlement. More digging coming up.
