When I see Birdy pictures I always think how people manage to not yank it out on the rough surface.
The Shimano Ultegra RD-R8000 I use is the SGS with a medium cage, its position to the ground is I think similar to the one of the SRAM Etap AXS. For those, there are two types, the older one that was going only up to 32t and the latest one that goes to 36t. There is also now the XPLR type for a cassette to 44t but tis cassette won't work on the Birdy (I think, I haven't tried it).

Yes, the Birdy without mudguard roll on its rear wheel without any easy wheels, but i need mudguards.
