I have used Selle Italia saddles on my Giant & The Verenti, my recently purchased Marin Gravel bikes stock saddle, didn’t seem that bad a fit & a little tweaking with the position and angle has proved to be a comfy perch, it’s really pot luck, my first road bike, a Carerra, had a saddle that must have been designed by the Spanish inquisition, as after 20 minutes you would have admitted to anything, it was dreadful no matter what you did.
i would recommend a visit to a decent LBS and get measured as first step, then get something that suits your sit bones, good luck !
