Out of the 15 you listed, two-thirds involve dividing by 3 and
one-third can be obtained by dividing with a binary integral
which IMHO is technically easier. The reverse is true with a
starting frequency of 2.4576, 4.9152 MHz, etc.
No it isn't. As I said before:

Using 300 multiplied by a power of two wouldn't give you any easy way to
obtain 14400, 28800, 57600 or 115200 (you would need to multiply by 3,
which is much harder than dividing by 3).
E.g. 2457600 / 14400 = 170.6666...

If you start with 2.4576MHz, two thirds can be obtained by dividing by a
power of two and the other third can't be obtained without a frequency
multiplier (VCO + divide-by-3 + PLL).

Divide-by-3 isn't exactly hard (if you want 50% duty cycle, divide-by-6 is
easier, and just as useful in this context).
