I Use Planet Fitness in my area, it is fairly inexpensive and people tend to be in their own little world so no issues at all. Also the gym itself has a policy of not bullying people or showing off, even has a big red ‘lunk’ alarm button on the wall if someone is out of line. I have never seen it used. The gym however is very lacking on personal trainers and the ones they have are just kids who do not have their head in the right spot. My main go to is actually the Workout for Woman app it has several workouts geared to different areas of the body or goals. The only short fall is the hip dips issue I have and I do not think there is a workout that will solve this.
However for body shaping I found side planks and mermaids do wonders especially if you do side bends along with them. I tend to stay away from most arm and shoulder stuff except stretching.
