Forget X570 for ITX, no benefit other than the second m.2 being PCIE4.0.
Select B550 among the ASUS (with me), ASRock (Phantom) or Gigabyte B550(with me).
Gigabyte/ASRock both got great VRM but no USB-C for the Giga and a lousy BIOS on both.
ASRock and ASUS have Intel 2.5Gbe which is a bonus.
The ASUS (short of a USB ports as you noticed) on paper is inferior but the BIOS n tuning makes up for it. On Zen2 I liked this most.
It however remains to be seen how much love ASUS will give to it regarding Zen3.
They have a pretty bad history of maintaining older AM4 boards.
If you like to tinker with your CPU/RAM, the ASUS would be my favorite.
If you don't do that take the ASRock for USB-C + Intel Ethernet or the Gigabyte for the cheaper price tag.
X570 Asus boards are the only ones with a respectable number of USB ports, although this has nothing to do with chipset and is just Asus product segmentation. It also appears that the X570 is closely priced or slightly lower than the B550 local units too if I try and import one. Otherwise I agree, nothing with X570 chipset makes it worth it over B550 for ITX.

Sounds like its safe to jump in with some nuances that need to be worked on.
Gotcha.
Which case are you thinking of getting? I've seen several builds with giga x570i with the c14s that fit fine but the case is the limitation, can't close top panel in the M1 for example.
I own two of these giga boards and they're alright. Never had to wrestle with it to get anything done. Oc/undervolt/fan/pump settings are straight forward, xmp sticks. Fan headers are limited but each header supports 24W which means you could power a ddc off one vs molex, not a big deal if you're thinking of doing air cooling though. The PCH fan is loud, but there's a BIOS update for that.
I've heard bad things about fusion, so might be best to avoid if you're into syncing rgb. I dont, so I just leave it the default orange.
This is all on ryzen 2 so I'm not sure if there's are issues with using ryzen 3.
C14S blocks top mounted fans in NR200, and can't be used in an Ncase with Gigabyte and MSI boards. Leaning towards either of these cases for the build.
