Hmm, well did you already check fuel pressure?

A lot of “popping” at idle *video*

Yeah. There’s a gauge at the rail. It’s 40psi
Well, I would check the following: voltage with the car running, any damage to the wiring harness for the ignition coil circuit and possibly throw a camshaft position sensor at this problem. I hate throwing parts at a problem, but without a scan tool, there isn't much other choice.
The misfire coould be throwing the camshaft sensor code and the camshaft sensor code cos be causing the primary ignition coil code..... Or funky voltage could be causing all of this.

I'm still stumped on the one spark plugs looking so clean compared to the others. That just leads me to believe it's contained to that one cylinder.

Me too. Currently on jack stands right now so it can’t be driven so plugs will have to wait to see how they look after the new set. Think it could be an o2 sensor?
I'm stuck on that clean plug. Bad o2 sensors wouldn't cause one plug to be that clean.

I really don't think that cylinder is getting a good spark for some reason.

My next step would be to buy or borrow one known good coil and move it around, starting with #7.
Yep, even though you done an ohm test, I would do this as well. Did you check between the pins on the coil and the side that connects to the spark plugs with a meter?

I have me a full set of 8 I swapped out because I thought it was causing a miss for me but I found out it was a cracked plug only after I put in the new coils. I still have them if you want them, they are just collecting dust right now

One lean injector could cause that issue.

I replaced all 8 coils with ford coils and all plugs replaced 3 times
Since you replaced all coils, I would check for a plugged injector and also make sure that cylinder is getting power to the coil.
Those two things are what I would do next.

How can I check an injector outside of resistance test?

There isn’t any real easy way to check an injector for flow. If you had a buddy that has the same size injector, see if you could swap it out for testing.
Since it Check good resistance wise, you need to make sure there is flow thru the injector. You did verify voltage, correct?

Getting worse it seems like
Can you datalog? This way you can eliminate any other issues that could be contributing to your problem.
You need to verify voltage to the cylinder coil that seems to be dead, make sure that injector is actually working and verify the cam sensor is working correctly as well.

Another thing you could have going on is the possibility of a furry little rodent has gotten into the wiring on your car and chewed up some wiring. Since your cars does quite a bit of sitting, this is a possibility. But I would verify all the other stuff mentioned first.
You’re at that point where throwing a scan tool on it may find the issue. It does seem to be getting worse.
