For that processor (2200g) any of the boards mentioned would be an ideal match. However, the Tomahawk (an ATX board, by the way) and Mortar Max are two boards that would be quite excessive for it. Still, they remain the top option if your future plans involve upgrading to a discrete GPU with a more powerful chip, such as 3700X or even 3900X.
What CPU is required? The VRM specifications differ between the Ryzen 3 1200 and the Ryzen 93900X. If you provide more details about your system, it would be helpful. You might also have an APU in use.
The top microATX overclocker for the B450 platform is the MSI MORTAR:

EDIT: It looks like this board isn't readily available at its regular price. Given your 2200G setup, I recommend the Bazooka. You might find useful information on Actual Hardcore Overclocking's YouTube channel about the best boards for OC APUs.
Would you be comfortable choosing the B450 Tomahawk?
Edit: The specs mention that the b450m bazooka can handle up to 2GB of shared memory, whereas the B450m HDV r4 supports a maximum of 16GB for onboard graphics. Will it be better to go with AsRock's model, or does the shared memory matter less?

Additionally, don't aim to overclock the 2200g CPU. Its capabilities are quite limited and mainly restrict the iGPU's potential for performance gains in gaming. Also keep in mind memory usage; overclocking RAM can noticeably boost gaming speeds.
I'm confident any memory constraints are tied to the processor type and the number of DIMM slots it provides. Both motherboards typically support 16GB of RAM, as they only require two slots, but the CPU will handle sharing based on its specifications. This might explain the 2GB (shared) figure. Where are you getting this information for the Bazooka? On the spec sheet I see:
4 DDR4 slots, capable of up to 128GB
Compatible with 1866/2133/2400/2667MHz (JEDEC)
Supports speeds from 2667/2800/2933/3000/3066/3200/3466MHz (A-XMP OC MODE)
The issue with B450 boards lies in the number of power phases they can handle. This affects how much current your CPU can draw before the system fails.
MSI did an excellent job with proper heat sinking.
ASRock performed adequately thanks to their high-current chokes and regulators on the steel legend.
The 2200g is a first-generation Ryzen CPU paired with Vega graphics. It isn’t even Zen+. Therefore, overclocking will be somewhat restricted. You could reach around 3.8GHz with sufficient cooling across all cores. Even I faced challenges getting my 3000 rated DDR4 memory to exceed 2933 MHz on a 2400g system.
