NGC 300 is a beautiful spiral galaxy but can seem rather plain looking with standard LRGB
processing, so I have used some Halpha (Magenta-Red patches) and OIII (Teal-Green patches)
to highlight the extensive star forming regions across the galaxy, they are everywhere!

Taken over 2 nights, no moon, seeing above average
That's what I mean, even though it's popular, it's a unique target for you that you haven't done previously as opposed to the 20th version. Another galaxy that has a lot of OIII is NGC 6822 and maybe IC 1613 in Cetus? IC 1613 definitely has lots of Ha, could do that next if you want?
It may be a popular target Sak but in over 34 years of astrophotography I had only imaged it once before...way back in 2005 with an 80mm refractor :-)

OMG you're so good at galaxies, I'm not even going to complain that it's a popular target because it's so beautiful! Very inspired idea to add OIII, M33 in the north also has OIII nebulae. My only suggestion would be to add a little bit more narrowband data.
