Under i will explain why i believe uzumaki/senju have been chosen over the uchihas for the Jinchūriki role, and why i believe the uchihas are just as fit for the role as the senju/uzumaki.

1. they are most trusted clans(senju and uzumaki) in konoha so it would be obvious they are chosen for the role.

2. it is not the special chakra or genes of those two clans (senju and uzumaki) which makes them fit for their roles it is the by-product of the chakra or genes, two common traits among the two clans is a strong life-force(more of a uzumaki-thing) and big chakra pools. A big chakra pool is necessary because the seal drains chakra and life-force incase the bijou suddenly are extracted.

3. So know we know the two most important requirements for being a functional Jinchūriki, but i would argue that an uchiha would need neither of these requirements to be fit for the role(even though many of them possess at least one of the these traits, a big chakra pool). Because if the uchiha is skilled enough in genjutsu he could keep the bijuu inside him in a constant trance, so there would be no need for a extremely strong seal as the one Naruto has. But rather just a weak seal that keeps the beast barely inside, because there is no fear of the beast slowly weakening the seal or draining the Jinchūriki's chakra, due to it at this point just being a big pool of chakra with no free will(because of the genjutsu)

4.But of course there are disadvantages to this method and the only one i could think of is that the uchiha would be unable to cooperate with the bijuu and be broken out genjutsu by it. But other than that i see no obstacle for the uchihas to become just as highly effective Jinchūrikis as the uzumakis have been.
