I cook the majority of my meals from scratch, stir-frys, pasta dishes, curry, chilli, casseroles, chicken/beef/pork with mashed/roast potatoes & veg. I live alone and with things like soups, casserole, curry & chilli dishes I deliberately make too much and freeze the excess so I've usually a meal to hand if I don't feel like cooking.

I must admit though that I'm not a big fan of fish and when I do buy any it is already frozen and covered in breadcrumbs. The exception being fresh salmon because it can be bought in small quantities and is nice for a treat.

The other things I buy frozen are pizzas and beefburgers. I don't eat them very often and to me it's not worth the trouble to make from scratch.

I don't make my own spaghetti, or other pasta, either again too much trouble. The dried is so much easier.

And I don't bake, that is something I just cannot master. I don't eat pies or cake often, or desserts if it comes to it, so it hardly matters.
