If you exercise regularly - how often? How many calories do you aim to burn over how long?
I do some kind of exercise most days. Some "rest days" are walking or gentle exercise like yoga or just generally being active.
I don't "aim" to burn calories, but as a short woman, regular exercise helps me to maintain a healthy weight on a relatively relaxed diet
If you don't use calories as a way of keeping track, what do you do?
I record data from my Garmin watch into an exercise log (notebook/ bullet journal) this helps me check that training is balanced, seasonal patterns, training plans.
For runs I train by time/ distance. Swimming by time. Other is just recorded. I know I'm progressing at circuits if I move up a weight.
Calories are pretty meaningless for assessing exercise benefits. One hour of running/ weights/ yoga/ swimming have different benefits.
For those who don't go to the gym - how do you exercises? Running? Exercise bike etc?
I run (and tend to have a race on the horizon at any point). Running is easily measurable. I like outdoor and group exercise. Both is even better. I do some short videos at home but struggle with longer workouts in that setting.
Do you use any aids that have really helped you with weight loss/toning up? I was thinking of getting a waist trainer but not sure if it's a waste of money
Not aids in that sense.
I have fitness equipment in varying states of use. If nothing else it reminds me not to join a gym 😂
I use my Garmin watch to record sport/ general activity.
I use apps such as C25k, strava, to record/ motivate/ share. Online discussion.
If actively monitoring my diet I use MFP
How many calories do you aim to eat a day?
If I'm monitoring my diet, I'll bring it down to 1600 as it's enough to fuel an active lifestyle. If I'm being active I typically burn 1900 average. I sometimes 5:2.
Most of the time I don't pay much attention.

I'd say from the questions that OP's focus on exercise is a bit the wrong-way-round and highly likely to fail.
I could say that spin and running marathons are great ways to burn calories and I wouldn't be wrong, but for most people it's not sustainable.
Think about what you find practical and what you enjoy. That will work longer term because you can and will want to do it.
For most people unless they put a lot of time and training into exercise it's pretty limited in the additional calorie burning potential. If your body burned 2000 on a regular day, most of that would be burned by generally existing. If you spent an hour blitzing a 10k run, you could burn 600 extra calories... BUT you can't do that every day, or even much more than once a week if that.
Better to focus on the other benefits of exercise. General fitness/ health, how you feel, healthier body shape, stronger bones/ joints, time outside in fresh air/ vitamin D, social time, stress relief...
Don't be dominated by scales either. Muscle is more dense and can hold water retention. Using a mix of methods including a tape meaure and photos is better for seeing progress.
