Like you i try to provide as much as i can for my guest. I keep it to the essentials though. No wine, beer, or soda. That leaves you open to other issues such as a minor getting it or it offending someone. I provide 2 bottles of water. I have coffee, tea, sugar, cream, mints in a bowl and a bowl of chocolates. Over time ppl have bought different seasonings that are left. I have a drawer that has travel size items in case they forget anything. We also are pet friendly so i provide the things needed to follow the rules. Poo bags, a leash, and towels to wipe them off should the weather cause issues.
What i have done is let my new guest know at the time of booking that i am willing to get any special requested items but they will have to cover the cost. I dont charge extra, just the cost of the item. ie flowers, bottle of wine, tickets to a function, or reserve a T time. Been doing this since airbnb started and ppl appreciate the extras but i hear more about my white fluffy towels or super soft white sheets, the deer, and about checking on them after their first night. Very few mention anything else. Save your effort but maybe leave it as an offer for those that want some extras.
Good luck and welcome to airbnb. I have never regretted doing this. I meet the best ppl and they really are just looking for a clean, uncluttered place to lay their head at the end of the day.
