Is it possible to seat the primers too deeply?

It should be fine, unless your firearm has a short pin or light spring, or both. No way to tell except heading off to the range with a box. Curious, have you uniformed the primer pockets? I have seen some really deep primer pockets from that.
I modified my RCBS seater to seat them in as deep as can be done without modding the pocket. I shoot ARs, and M14s, and deep is good on a floating pin. So long as your pin can reach them, you'll be fine.
A "wrong" primer might be a pistol primer in a rifle case - I suppose. That would seat very deep - and pressure would be excessive for the softer pistol primer.
Maybe you are getting a bit energetic on the priming force - just do one too light, then use multiple strokes - until it is properly seated - and learn the force required and the feel of it bottoming out.
The primer should be flush or only slightly below casehead surface - never proud of the surface - I guess you likely knew that.
Go easy on the pocket cleaning - I seldom clean pockets - to avoid getting loose pockets. The little Lee tool only cleans the bottom, whereas a brush tends to abrade the sides a little.

if the primers arent sitting right down in the pocket you could have FTF. Sometimes the pin strike just pushes it down a bit, and doesn't get a sharp enough strike to set em off. I'd take your hand tool and re set them all.
