All of the traditions of Buddhism are full of practices and advice that can immediately benefit you and those around you.
You don't have to put some abstract statements in the "true" basket to get past the front gate.
Buddhism is concerned with suffering and the end of suffering
. Not collecting shiny new ideas and practices to put on a shelf.
It's said that there are 84,000 gates to the Dharma. Our particular mix of suffering is so different from person to person. There's no single statement or idea that will solve our problems. We just have to start where we are.
For me, that was mindfulness of breath meditation, called anapanasati. I had no patience for metaphysics, and I was able to benefit immediately. I recommend looking into this.
Thinking things like "I have ten fingers and also I was a fat cobbler in Europe in a past life" is hardly the same thing as insight gained about your pain, earned from steadfast meditation.
By practicing basic ethics and meditation and exposing yourself to Buddhist teachings, at the very least you will find your suffering diminishes.
Yet this is overlooked as some people deem something like Buddhism as "unworthy" based on a thought barely two sentences long.
Consider also that in the question "is rebirth real/true?" we often have the standard "...as real as I am and my perceptions are?"
This "me" and "my perceptions" are a large focus of Buddhist practice and meditation. You may discover some interesting things about them in time.
And at a later point, who knows? It might become useful to take things like rebirth or karma as a working hypothesis. They are there for a reason, even if we can't see it from our current vantage point.
Best of luck! I hope that whatever you do, your suffering diminishes and your happiness increases, in this very life
