I have both Bluez and Blueman installed... neither will find any bluetooth device I have. Nothing they just search. And I can't see it with my phone. My old laptop no problemo!

First of all, I feel your pain. I have struggled with bluetooth way too many times, to the point I use it as little as posible. ( end of rant ).
From your posting, some things look good. rfkill results are fine. YAY.

Bluetooth: hci0: Failed to read codec capabilities (-22)
I did a little research, apparently that is a kernel bug fixed in a new kernel version. The good news is bluetooth still works, even though you see this error. For now you can ignore it.
I learned a long time ago the gui's for bluetooth don't provide much information, if they did you would be as frustrated as you are now. So, open a terminal, and run bluetoothctl. That need root privledges, so 'sudo bluetoothctl' should give you a bluetoot prompt. Type help to see the commands you can run. This is what it looks like on my system.

The show command dumps out some nice info on your server side controller. Run the command and post the results.
You can try to run the scan command. That looks for devices you might want to connect to, ie pair. Give that a go and post the results. Once again, here is what it can look like. After letting it run a few seconds, this is what showed up.

I have a bluetooth speaker that my Linux Mint system will connect to no problem. But it's not even seen by this system here. The only reason I am using Kubuntu is it's the only distro that would see and use my WiFi card. No amount of cajoling would get Mint to see it or use it. I even used a Linux supported WiFi dongle to no avail.
Bluetooth is the last thing I need to get working on this system. I use it to connect my hearing aids to my laptop so I can listen to training videos or watch movies without disturbing people around me ( I'm deaf as heck ). So for me Bluetooth is important.
I finally hacked bluetooth into working here on my laptop once, and managed to transfer test files both ways. Then I promptly gave up on the thing. It's too much of a PITA.
I used bluetoothctl for setting up everything, and blueman(?) for file transfer. Bluetoothctl is a terminal tool. YMMV with other tools. With bluetoothctl, you have to
Get the card up.
Search & Find your target.
Pair your devices.
Trust your devices. I think trust is not bi-directional so you may have to trust incoming and outgoing separately.
Bluetooth was invented in the last milennium and IBM guys waxed eloquent about it. They envisaged it used for controlling huge corporations. So the board members might get the new combination to the safe, or part thereof. And you could send them the new combination on their pagers every week.
Board members might also get the root password for the mainframe along with all sysadmins, but the sysadmins could never get a bit of safe combination, etc. IBM were dreaming - not for the first time either.
In fact, we all want to do is drive a coach & four through the security and transfer data fast.
Do you have any other bluetooth device, like a smart phone? You can scan with android phones.
I don't know much about bluetooth speakers, might be worth looking at the doc to see what procedure is used to pair.
I also don't see any abvious problem with your system.
I would look into the bluetooth versions, to see if there is some incompatability between the two devices in question. Look at the firmware level for the bluetooth adapter, and search for any clews.

These comments lead me to believe you have some very new hardware in this box, so I'm thinking incompatability is most likley the problem.

I would tend to agree. I had to 'upgrade' my older Linux LTS on my file server to latest KUbuntu 22.04 so Linux would recognize the 2.5Gbit ethernet PCI card I had upgraded too. That said, so maybe you could buy a cheap BlueTooth dongle (use a USB port) to test the theory out?
So I bought a Linux supported Bluetooth dongle and viola! Stuff works! Yes the laptop is pretty new, Ryzen 9 should be a good indicator... anyhow thanks! Guess I'll have to wait until the installed Bluetooth is supported. For now though I can use the dongle.
