Welcome. Yes the cakes and biscuits will do you no favours unless you make your own low carb ones for which there are plenty of recipes. However it is all carbohydrates which convert to glucose not just the 'sweet ' stuff. Berries are good being the lowest carb fruits but tropical fruits like mangoes are very high. Vegetables and salads are a better option than too much fruit.
What may be a heathy diet if not diabetic is not so if Type 2 diabetic.
Meals based on meat, fish, eggs and cheese with veg and salads but only very small portions of any of the higher carb food like potatoes, rice, pasta, bread, breakfast cereals which are the big hitters.
Have a look at this link for some ideas for modifying your diet, it is a low carb approach which many find successful, there are some do's and don'ts and some menu plans to suit various tastes and budgets.

The two medications you have been prescribes work in different ways, metformin helps the body use the insulin it produces more effectively and if the other one is gliclazide then that encourages the pancreas to produce more insulin.
That one has the potential to cause low blood glucose so your GP should have prescribed a monitor and test strips and lancets, if they haven't then ask.
