What evolutionary benefits does the transition of plants to seed propagation provide?

Seeds are more viable. thanks to animals, wind, water can be transported over long distances. There is a supply of nutrients.
The transition to seed propagation has given plants many advantages: the seed germ is now protected from the adverse conditions by the membranes and provided with food. In some gymnosperms (conifers), the process of sexual reproduction is no longer associated with water. Pollination in gymnosperms is carried out by the wind, and the seeds are equipped with devices for the distribution of animals. All this contributed to the resettlement of seed plants.
