@Holli92 Whatever you do, the most important thing is to set accurate expectations in your listing and make it very clear that the home is your residence and not 100% a holiday home.
1) In a whole-house rental, guests expect the fridge to be empty so they have plenty of space for their own groceries, and no perishables to deal with. Some bottled drinks or condiments for guest use are sometimes welcome, although it might be good to check with the guests on that first. As for the pantry, I'd recommend having things like spices, oil, salt, sugar, coffee, and tea available to guests, but if there are personal food items you don't want them to use, they're best stored somewhere else.
2) Zipties are easy to break and replace, so I really see no point in using them to secure your personal items. Padlocks are fine, but guests will still want storage space for their own belongings, especially during longer stays.
3) Cleaning supplies are essential, and it makes your changeover easier if guests have all the means to tidy up after themselves easily right at their disposal. I like to have a convenient device to make coffee (which doesn't involve single-use plastics), well-sharpened knives and wide cutting boards, some potholders and tea towels. I'm not too big on novelty gadgets and kitchen electronics; a well-stocked kitchen will have sturdy utensils and cookware but it doesn't need a Keurig or an avocado slicer or a Margaritaville machine.
