This is not like Hebrew, modern or paleo. The Hebrew, Phoenician, and Proto-Sinaitic alphabets were purely phonetic, they just happened to not represent vowels (only consonants). But there were no ideographs involved - the system was derived from Egyptian hieroglyphics, but it did not preserve their meaning, only preserving them (in much-simplified forms) as mnemonics for the sounds. Similar to the origins of the Japanese kana system, but NOT its use of kanji.
I'm not following you too much, I'm not saying it is like Hebrew modern or paleo. I'm saying it's like Ancient Pictographic Hebrew[0]. Each character has a meaning, and they're simpler than the second character shown in the article to register (though in their defense that character is likely made up of variations of a couple of other characters). Also, the Hebrew didn't have vowels up until the Masoretes who added to the Hebrew Scriptures by adding vowels to them, but that's another topic not related to this topic.
