Evidence for intensive contacts between Proto-IE & Proto-Semitic

As already explained with a footnote, the idea that early Proto-IE speakers and Proto-Semitic speakers were in contact with each other isn't controversial, but debate continues on as to how, where and when they were in contact with each other. The neolithic is really the most sensible time for this to have occurred since it gives widening trade as a motive for this cultural and linguistic exchange. The how is clear then: growing trading networks in the Neolithic and exchange of goods. The relations at this time between the Balkans and Syria are reflected firmly in archaeology which show commonalities in ceramics and material culture. However, Neolithic trade only gives us a window between 6000 and 4000 BCE, so as far as I'm concerned, the precise "when" is too obvious to feign confusion. The matter of where this contact occurred continues to be a senseless debate, egged on by sensationalists like Ivanov and Gamkrelidze who attempt desperately to place Indo-European in Anatolia. It doesn't fly. The least controversial hypothesis is that PIE was centered around modernday Ukraine and there's no reason to rebel against this economical view. However, it must be understood that if this contact started a millenium or more before PIE proper, there's no guarantee that earlier stages of the language existed further to the south as I suggested earlier for the stage of PIE I refer to as Mid IE (MIE).
So let's get straight to the chase and start mapping the possible loans from PSem into PIE and see how intensive this contact might have been:

content verbs:

PSem *šáðrawu 'he causes to scatter (caus.)' (root *[ðrw])
=> PIE *streu- 'to scatter' (via MIE *satréwa-)​

modal verbs:

(?)​

existential verbs:

PSem *yiθ 'there is'
=> PIE *ʔes- 'to be' (via MIE *es-)

PSem *báwiʔu 'it is come (stat.)'
=> (?) PIE *bʰeuh₂- 'to appear, to become' (via MIE *béuxa-)​

content nouns:

PSem *θáwru 'bull'
=> PIE *táuro- (via early Late IE *tä́urə-)

PSem *gádyu 'kid, young goat'
=> PIE *ǵʰáido- 'goat' (via early Late IE *gä́id̰ə-)

PSem *sábʕatum 'seven'
=> PIE *septḿ̥ (via MIE *séptam)​

pronouns:

PSem *šu 'him, himself'
=> PIE *swe 'oneself' (via MIE *sʷa).​
