Some type of Oak as can see a few lobes in first pic? AI says

Its the guards plus stakes which have caused problems were they larger trees which is imo a bad idea for such large volume plantings? If your stake is attached low down as possible so top tree can move in the wind the trees will develop alot better root anchoring but then this would not support the guards..... If staked low by the time the stakes fail trees will hopefully have anchored its self.... I once made alot of stakes from free larch sawmill offcuts

I don't think that species can be overwatered as looking up info says they grow in water logged conditions naturally AI/google says River birch trees are particularly susceptible to developing iron chlorosis (yellowing of leaves) in alkaline soils. This is because the high pH of alkaline soil makes it difficult for the tree to absorb the essential nutrient iron. Some infos River birch might be a lost cause - West DIGITALEDITION.CHICAGOTRIBUNE.COM But apparently Wake county NC is mostly acidic.... Soil Survey of Wake County, North Carolina : United States.

Well its very often true.

Id also consider the makita 40v platform as batteries are free on promotion atm with each new tool and the cost of batteries is a big % of total cost So you could buy 3 tools & get 3 free 40v batteries I think.. Makita - Products WWW.MAKITAREDEMPTION.EU Agree about blowers they are very battery hungry. If you look on yotube there some reviews of the makita products If you look at the Kw rating of the electric motor in the various toppers compared to a 200t will tell you roughly how rapid with it cut in comparison. So the msa220t for example should cut about the same i reckon as a ms200t.
