A lot of people giving good advice at how to become good at cooking. I will give advice at how to coom at a bare minimum level.
Pasta
Boil according to Pavket instructions, add jar of sauce. You have cooked a totally legit meal. Consider leveling it up by adding cooked meat/vegetables to the sauce. E.g. fry bacon, chop it and add it in. Mix in spinach leaves.
Pizza
Buy a pre-made pizza base, cheese, "pizza sauce" and your favorite toppings. Assemble and put in the oven for like 20 minutes. Topping ideas include all cold meats, e.g. pepperoni, whatever vegetables you like, e.g. capsicum, and anything from the jarred food aisle. E.g. olives, artichoke, eggplant.
Chicken
Buy Chicken breast, buy a spice mix which looks nice, buy a thermometer. Coat the chicken in the spice and cook at 180 degrees C until the temperature inside the chicken reads safe (often the number is printed on your thermometer, or just Google it) this might take ~20 minutes
You can eat this with a salad you also bought, chop it up and add to tomorrow's pasta, or to sandwiches, on a pizza base.
egg and rice
Cook rice according to packet instructions, fry an egg. Add on your favorite chilli sauce. I go through a jar of Chilli Crisp (Lau Gan Ma) every two weeks thanks to this one.
First decision is if you want a resin printer or FDM printer. Resin let's you get smaller details, but has less dimensuonal accuracy and less options for engineering material.
In practice this means that if you want to make highly detailed descriptive parts. E.g. figurines, jewlery, etc go resin. If you want to build functional parts, latches, anything that moves, or anything that is big go FDM
From your description it sounds like you want FDM
My only experience with FDM is BambuLab which gets called "The Apple of 3D printers" for better and worse. I can personally say they work fantastic, and "tuning and maintainance" of the machine is almost non-existant. HOWEVER there is a little proprietary schenanigans going on. Their system is still open for now, but people worry because hypothetically in the future they might take functionality away or something. (There is a long and boring list of controversies which could be a deal breaker or nothing burger based on your preferences. For me I find it an okay tradeoff for the performance)
