You have some good specific recommendations from @sobuddywhoneedsyou@lemmygrad.ml, so I'll talk more about high level, type stuff.
I'd worry less about the specific amount of weight and reps and more about RPE (rate of perceived exertion). Make sure you are pushing yourself to change through progressive overload. I don't know what your progression plan is, but if you don't have one, you should consider having a plan in place. You need to stress the body to change or it won't, that includes muscle growth, strength or whatever your goals are.
That leads to my other point, it's great to get active and improve your health, but part of what will inform a good program is what your goals are. Are you looking at health, practical strength, sport, aesthetics? There's overlap in all of those, of course, but knowing what you want out of your time at the gym can better inform what you want your routine to look like.
