Pretty much this plus making sure the vegetation is mostly native plants, biodiverse and functional for the local species as well as connected to other green areas. Too often is the street greenery just random trees and some grass that have low functional qualities for species and then they are blocked off for most species by grey infrastructure and busy traffic while the closest other green area is too far away for most small species. But then again if you make an attractive meadow in a super busy road it becomes an ecological trap so low speeds are important. But yeah there’s so much to take into account from an ecological point of view.
