Smaller charities tend to do much better in my experience.

UBI is not charity. UBI is what the nation owes you as a shareholder of USA, Inc.

Giving people money doesn’t teach long term skills that lead to success.

Exactly. Which is why the children of rich people so often become homeless. All that money they had when they were kids kept them from learning long-term skills that lead to success. It stunted their financial growth, rendering them particularly susceptible to poverty.

The children of the impoverished, on the other hand, were forced to learn money management skills for their very survival.

This explains why self-made millionaires are so common, and generational wealth is so difficult to achieve.

I also think it would be better to have private organizations that have less bureaucracy.

Agreed. An organization doesn’t get smaller or privater than a single individual. We can cut out 100% of the bullshit bureaucracy and give it straight to the individual, directly, or their caregiver if they are not qualified to maintain their own affairs. Remove everyone else, as they don’t add shareholder value.
