I am looking for opinions on a budget friendly way to drive 10 groups of 4 LEDs with each group emitting in a sequential order and a changeable direction when needed..
40 WS2812 LEDs, any Arduino and an external power supply capable of providing the required current

As suggested a Neopixel Strip and then define groups of 4 LEDs.
Just as an Idea:

I agree: programmable leds are the thing here.. You can always change the size of your array from 10x4 to whatever.
in addition: any ESP, Teensy or just a 328P can handle that too.

What kind of LEDs?
I had the ESP in mind at first but unfortunately it can only outputs 3.3V and as I understood these programmable LEDs need 5V..
Any low powered would do the job (through hole LEDS) etc..
Then put the LEDs in a matrix wiring configuration and use a HT16k33 backpack. But I forgot to ask specifically, RGB or one colour?
Also what is your experience level?

Will that matter as you will not be powering the LEDs from the board anyway

No problem. The supply of the LEDs is 5V and the esp has its own 1117c regulator for the 3.3V. this works fine
