I heard it’s either Egyptian or Semitic
Mainly basing this on ancient influence to each other and not direct tree splits:
Omotic has the most Cushitic loanwords because of Sidamas and Oromos influencing them for a very long time. There is a thing called the Ethiopian sprachbund area.

Chadic may be from North Chad or West Sudan originally. May have had direct ties with early Cushites.
Then maybe some ties to Egyptian due to the geographic area the first Cushites were in.
Berber and Semitic, probably the least (Arabic and Ethiosemitic loanwords shouldn't count).
How come reer waqooyi dialect uses alot of dh instead of the R?Proto-Semitic:
1sg. c. *ˀaḏkur
2sg. m./3sg. f. *taḏkur
2sg. f. *taḏkurī
3sg. m. *yaḏkur
2d. c. *taḏkurā
3d. c. *yaḏkurā
1pl. c. *naḏkur
2pl. m. *taḏkurū
2pl. f. *taḏkurna
3pl. m. *yaḏkurū
3pl. f. *yaḏkurna
And here is the prefix conjugation of the verb "to say" in Somali (one of the 5 irregular verbs that retain the prefix conjugation in this language):
1sg. c. idhi
2sg. m./ 3sg. f. tidhi
3sg. m. yidhi
1pl. c. nidhi
2pl. c. tidhahdeen
3pl. c. yidhahdeen
And finally here is the prefix conjugation of the verb "to kill" in Tamazight:
1sg. c. ∅nɣiɣ
2sg. c. tnɣid
3sg. m. inɣa
3sg. f. tnɣa
1pl. c. nnɣa
2pl. m. tnɣam
2pl. f. tnɣant
3pl. m. ∅nɣan
3pl. f. ∅nɣant
As you can see, the languages Berber , Cushitic and Semitic share a considerable about of features not shared with other Afro-Asiatic branches.

Like tiri instead of tidi for example
