Seeking Advice: Essentials for living alone

I'm planning to start living on my own soon and I'm trying to compile a list of essentials I may need. Highly confused on what all should be my essentials tho. I would greatly appreciate your advice on a few key areas:

Kitchen Essentials: What are the must-have kitchen appliances and tools? Also, which spices and pantry items should I always keep stocked?

Security Measures: Living alone for the first time, I want to make sure my home is secure. What security devices or practices do you recommend to feel safe and secure?

General Home Essentials: Are there any general household items or gadgets that you’ve found incredibly useful while living alone?

Thanks in advance! :>
