They are Bantu.
Omotic genetics are not found in Somalia.
Somalia only has ethnic Somalis (Cushitic in origin), Bantus, and Somali-South Asian Mulatto Benadiris. That's it.
Here is the UN position:

"A second minority category includes the diverse group of farmers who are not ethnic Somalis, living in much the same areas as the Rahanweyn and Digil. They include remnants of indigenous peoples, some of them originally speakers of the Cushitic languages (such as the Shebelle and Gabaweyn) and some Bantu. These peoples are mostly culturally assimilated to the Rahanweyn. The other groups are descendants of former slaves who established enclaves in the 19th century, chiefly in the Lower Shebelle and Lower Jubba valleys. Originally having retreated to the tsetse-infested woodlands on the riverbanks where no pastoralists ventured, they are often collectively known as WaGosha, "forest people". Many of these communities retain Bantu languages."
The Makanne and Shidley are covered in separate papers.
