Whenever I need to find keybindings, I resort to database searches:

MariaDB [mythconverg]> select * from keybindings where
hostname='mypvr' and description like '%pause%';
+-------------+------------+----------------------------------------------------------+---------+----------+
| context | action | description | keylist | hostname |
+-------------+------------+----------------------------------------------------------+---------+----------+
| TV Playback | PAUSE | Pause | P | mypvr |
| TV Playback | FFWDSTICKY | Fast Forward (Sticky) or Forward one second while paused | >,. | mypvr |
| TV Playback | RWNDSTICKY | Rewind (Sticky) or Rewind one second while paused | ,,< | mypvr |
| Music | PAUSE | Pause/Start playback | P | mypvr |
| Weather | PAUSE | Pause current page | P | mypvr |
+-------------+------------+----------------------------------------------------------+---------+----------+
5 rows in set (0.01 sec)

The p key for pause is used in the "TV Playback" and "Music" contexts
- if you change it in one, you probably should change it in both. I
ignore "Weather" as I do not have it installed. Do not forget to also
search the jumppoints table when looking for keybindings:

MariaDB [mythconverg]> select * from jumppoints where hostname='mypvr'
and description like '%pause%';
Empty set (0.00 sec)

I would not have thought there was any problem with XFCE and the p key
though - so I obviously am missing something about how your RF remote
works.

I'm pretty sure my remote's pause/play button is being trapped by the
Desktop environment because I can define another unused remote button to
the TV Playback 'pause' function in Edit Keys and that works.

I could always put stickers on the remote buttons LOL

If p was being trapped by the desktop, that would be very unusual.
Desktops almost always use Alt- or Ctrl-Alt- keys for hotkeys. And if
you do p on the desktop, you would hope that you would see something
happen as a result. I am still on Xubuntu 18.04 and there in the
Setttings > Window Manager > Keyboard tab I can not see any single
alphabetic keystrokes, and no p key. For the obvious reason that if
you wanted to type p into a field in a program, you really do not want
it grabbed by the desktop before it gets there.

What sort of remote is it? How does it interface with the system?
Does it have any testing software? Is lirc running and grabbing
keystrokes from the remote somehow?

The remote is an Air Mouse as shown on the wiki:
https://www.mythtv.org/wiki/Air_mouse_rf_remote
It's RF and connects via USB receiver.
lirc is not installed
Here's what I just did. In Settings -> Keyboard -> Application Shortcuts.
I added a shortcut to run mate-calc if I pressed my remotes >|| button. It
created the short cut noting that the key would be the AudioPlay. However
this didn't work as something else has captured the AudioPlay button.
That's why mythfrontend can't set that button to pause.

Ok, it is just a mouse and keyboard as far as the system is concerned.
So you should be able to use it in a terminal session and see what
keystrokes it is producing when you use the pause button. Or install
screenkey:

https://www.omgubuntu.co.uk/2016/11/screenkey-show-key-presses-screen-ubuntu

It should be available as a package:

apt install screenkey

When it is running, screenkey shows the keystrokes as they happen in
an overlay band across the mid-bottom of the screen and makes it easy
to see what each keystroke is.

Screenkey shows XF86AudioPlay when I press my play/pause button
It's the same code that's generated on my keyboard with FN+F8.

That makes sense. I seem to remember that mythfrontend does not
handle Fn-Fx keys. Maybe they are encoded as more than one byte? Is
there any way to change what keystroke the remote sends? It may also
be possible to remap it at the kernel keyboard code level. A quick
search gave me this page:

What you really need to do is disable the mechanism that grabs
multimedia keys before they get to the application. Then the edit keys
will see them. Each version of Ubuntu has its own method of doing that:

Ubuntu (this may be out of date):

use dconf-editor org.gnome.settings-daemon.plugins.media-keys and remove
the
actions from keys (next, pause, play, previous, stop)

In Xubuntu:

in the panel preferences find the pulseaudio plugin(volume control),
Right Click, Properties, media players. Disable "Control playback of
media players".

WE HAVE A WINNER!

It was right where you said on Xubuntu. Didn't even have to reboot.

If you want to double check if the desktop environment is trapping those keys, try using "xev". It's an X application that prints out the keys is sees as you press them, including shift like keys (e.g. Ctrl, Alt, etc). If the desktop is not trapping the play/pause key, pressing it should show up as XF86AudioPlay. But that's not what you would put in your keybindings table. It has to be what Qt calls the play/pause key, which is "Media Play". You can find what Qt calls other media keys in the source file:
https://code.qt.io/cgit/qt/qtbase.git/tree/src/gui/kernel/qkeysequence.cpp
