Almost everywhere in Thailand is friendly, so that's not the issue. Jomtien, and even more so Pattaya, have Freelancers hookers in the streets. A lot of sexpats. Ofc, you'll know where not to go, but the exposure will never be 0. I find Jomtien beach to be quite dirty overall and overcrowded. Imo, you would be better of in a city where people actually retire there with families like Hua Hin with higher quality of other foreigners. Phuket is too expensive. Chiang Mai would be even better but no beach. People go to Pattaya went they don't know any other options to start, but it's rarely their end destination. For your situation, you don't want an overcrowded area imo.
