Thats exactly it. Oda had an interesting setup with Kinemon and Momo but he really tarnished it and their perverted attitudes really didn't help.
I was shocked that Kinemon wasn't Momo's real father after all but tbh I did find him obnoxious and annoying back then with his fart talking too. He had a nice moment of kneeling to and being grateful at Sanji though.
Complete truth in what you said there, I've seen female OP fans swoon over Zoro and especially Sanji surprisingly, saying they prefer him. Oda definitely designed them to be desirable and be more eye candy as opposed to Luffy with his design and personality. I'm not sure if girls and women do swoon for Luffy too but they are definitely role models for the fanbase and extremely popular for good reasons ofc.
I grew up idolising Zoro and Sanji too with OP as well.
Toei have made the Scabbards look amazing though especially in this one scene by a certain amazing American (now living in Japan ofc) animator called Henry Thurlow:
