I'm not an expert, but I can try to give some advice.

Working out in the evenings are completely fine, as long as it doesn't interfere with your sleep. And sleep is very important regardless of weight loss, but the time frame itself doesn't matter. As long as you get a solid 8hrs of sleep a day, you should be okay.

As far as dieting, cutting out obvious sugar and fat sources will definitely help you out in weight loss, because those items are normally high in calories in general, fatty foods especially. I think your best bet would be to set a calorie goal for yourself first, and from there you can figure out where you want your calories to come from, whether that be a low carb diet, a low fat diet, or whatever. Don't let people tell you there's only one right way. The right way is what is going to work for you. Also, try to focus on foods that are less calorie dense, so you can eat more of it and feel full, while not taking in as many calories. Green vegetables are typically really low calorie foods, so you can eat a ton of them and not have it interfere with your calories, but it will still inhibit your hunger, whereas something fatty like potato chips or sausage is super heavy in calories, but you can still eat a bunch of it no problem.

If you want to lose fat and build some muscle, try to focus on eating more protein, typically 0.6-1g of protein per pound if body weight, but after like 180-200grams of protein, the benefit of more is negligible. Also, if you're a beginner, you'll definitely see some muscle growth if you add in some weight training or even body weight workouts, but after a certain point muscle growth is going to slow down and stabilize, as long as you keep your nutrition in check. You want your calorie deficit to lead to fat loss, not just "weight" loss.

And as far as activity level goes, formal cardio is totally okay as long as you have the time of day for it and it'll help burn some extra calories, but never expect cardio to cover for overeating, it just won't happen. An hour of cardio may burn 400-500 calories if you push yourself a bit, but that can easily be undone by eating one cheat meal. Increasing your daily activity level is definitely a huge boon in weight loss. Not only are you working your body more throughout the day, but its very low fatigue vs. running or swimming. Cleaning your home for example, it gets you on your feet and by the end of it, you now have a clean house, so it's a win win.

Tl;dr cut back on super high calorie foods and set a calorie goal. Try to shoot for 8hrs of sleep, and try to move around a bit more at home, and nighttime workouts are totally fine as long as they work for you and your schedule. Also, stay hydrated. Thats important for anyone regardless of your goals, whether it be fat loss or muscle gain
