I saw that video, too! Serviceberry are good for what ails ya! Our variety is ‘Smokey.’ We planted three.
But, I planted them because they’re so pretty when in bloom and the Cedar Waxwings LOVE them - so they get all the berries and I get to watch those beautiful birdies while I work in the garden. ;)

We have serviceberrys all around the house in the woods, maybe more than a dozen. One is near to the house. But I don’t know which kind of serviceberry it is. Berries are very small and the birds especially the cardinals really enjoy them. And you are right the blooms are great to see in the early spring.
