We could maybe eventually load up multiple asteroids with building materials, frozen embryos, a self-healing nanobot factory, blueprints for building artificial breeding chambers and humanoid robots, controlled by an AGI to serve as educators, and send them off to nearby stars.
Upon arrival on suitable planets, the systems wake up and jump-start colonies.
After several hundred or thousand years of development, those colonies could build their own seeder asteroids, kicking off an exponential progress.
If every colony in turn colonizes 4 new systems within 10,000 years, we could theoretically colonize every suitable star system in the Galaxy after 200,000 years. At a very reasonable ~0.1% of light speed.
But we would have zero control over the colonies, no shared culture, no trade, hardly any meaningful communication. So there would be very little benefit to it, and knowing human nature, a war of total annihilation would be likely as soon as suitable planets get scarce.
Intergalactic travel will never be possible for humans.
The nearest galaxy is 2.537.000 light years away. By the time we get there, we wouldn’t be humans anymore.
