Do not leave prosecco. It is a business relationship. Your tenant wants you to be professional, not nice.
You may end up liking your tenant, you may not. You want them to pay their rent and look after your property. They want you to recognise this is their home, and to maintain it, dealing with problems promptly.
Use an agent.
If not start with a prof clean (with receipts) and a prof inventory. Consider employing a gardener. Leave them a list of plumbers, electricians, locksmiths etc and explain clearly what they can and cant do in an emergency. Guarantees and service arrangements?
Leave them a couple of storage heaters should the boiler go. Leave keys somewhere accessible should someone need to get into the property quickly.
A good agent will have access to responsive workmen. They will be putting good business their way so the workmen will respond quickly.
I don't manage that many properties, but in the in the past few months I have had a shower trap fail, with water pouring down through the ceiling, the join in a central heating pipe go, so no heating or hot water, damp behind kitchen units from damaged caused by earlier tenants, a washing machine breakdown, some issues with rent payment that needed a face to face conversation, and now, the need to deal with an expansion to licensing requirements.
In an emergency some tenants are happy to work from home and wait in. Others not. Some I would not trust to oversee the delivery and installation of, say, a new washing machine, others I would.
And this is before you start on on legal stuff. Do you know what a Section 21 Notice is? What would happen if the lovely family were fronting for a cannabis farm. It happens.
Use an agent.
