Practicing architects and specifiers, what resources do you use to choose products for your projects?

Practicing architects and specifiers, what resources do you use to choose products for your projects? Do you use product directories like Arcat, Sweets, or Architizer? Do you use products listed in your office master spec, or from a spec writing service like AIA MasterSpec, Chalkline VisiSpecs, or RIB SpecLink? We are a building product manufacturer seeking to understand better the resources architects use in 2025.
