Enterprise Wifi Resources

I've been tasked with determining the feasiblity of providing wifi in one of our parks in Philadelphia. The idea is to encourage people to come and work outside when the weather gets warmer (WFP instead of WFH). I've never done anything on this scale but am sure it involves considerations of the following:

• The internet access itself (is gigabit fiber enough or is 10Gb necessary?)
• Designing AP locations
• Selecting enterprise level switching and equipment
• Content filtering and intrusion protection
• Revenue Generation

I don't know where to begin, especially when trying to come up with a round number for costs. I have the google, but it would be helpful to have someone with experience point me towards a concise definitive source for information.

Thanks in advance.
