My kids go to a montessori elementary school. We haven't seen those particular challenges, but I think a lot depends on the particular student and particular school.

There's not a lot of research on the outcomes for students who go to montessori, but what is available is mildly positive.

There is a survey of the literature published in Nature that concluded that the effects are somewhat positive, but since different schools apply the Montessori method in different ways, it's hard to say:

There's also a study from last year that says Montessori education is associated with positive well-being in later life. They control for a bunch of factors, but it's just association (not claiming causal):
