Audio
I'd guess the issue with audio playback is that all instructions/install scripts put stuff in /boot/config.txt which is now just a file that reads:
DO NOT EDIT THIS FILE
The file you are looking for has moved to /boot/firmware/config.txtWhich is rather unhelpful.
I'm reasonably sure you can just add dtoverlay=hifiberry-dac to /boot/firmware/config.txt and at least the audio side of pHAT BEAT will work fine.
LEDs
For user control of the LEDs you'll eventually be able to use pimoroni/apa102-python#9
That APA102 library (which is what the LEDs on pHAT BEAT are, fundamentally) needs some updates with all the stuff I've learned over the last few months before it's ready for prime time though.
Buttons
These are just regular GPIOs on the following pins:
BTN_FASTFWD = 5
BTN_REWIND = 13
BTN_PLAYPAUSE = 6
BTN_VOLUP = 16
BTN_VOLDN = 26
BTN_ONOFF = 12
They're active-low, with a pull-up so you can probably just try the following in /boot/firmware/config.txt to see if it works:
dtoverlay=gpio-key,gpio=5,keycode=163
dtoverlay=gpio-key,gpio=13,keycode=165
dtoverlay=gpio-key,gpio=6,keycode=119
dtoverlay=gpio-key,gpio=16,keycode=114
dtoverlay=gpio-key,gpio=26,keycode=115
dtoverlay=gpio-key,gpio=12,keycode=166
With the expectation that this will make those buttons behave like volume up/down, prev/next, play/pause and stop keyboard media keys. (I haven't tested this!)
The event codes header, that serves as a lookup table for the keycode, value is here: https://github.com/torvalds/linux/blob/e67572cd2204894179d89bd7b984072f19313b03/include/uapi/linux/input-event-codes.h#L189-L190

Adding dtoverlay=hifiberry-dac to /boot/firmware/config.txt get me passed the GPIO errors, but the errors about the profile persist and there is no sound yet. Any further ideas?

I can't believe I'm writing these words, but Unable to autolaunch a dbus-daemon without a $DISPLAY for X11 suggests audio wont work without booting up into Raspberry Pi Desktop...
Are you running the full desktop or Lite flavour of Pi OS?
What are you launching to try and get audio playing?

yeah, I guess I should have read all the way to the right :)
No, it's just the Lite version of Pi OS. I'm using it as a headless radio player. I've added some MQTT subscription in the phatbeatd code, so that I could remotely turn on the radio, that's why I don't need the buttons and the LEDs.
Let me try to through the desktop onto this machine then

Do you have any luck running something simple like: speaker-test -c2 -twav ?

hm, I guess a little bit of UI didn't help.
