How to explore varanasi

Har Har Mahadev I am visiting Varanasi next month for 3 days. We are 5 people -Me with my parents, my wife and son (2Yr). I want suggestions on how to best explore Varanasi in these 3 days, like from where to start, how to go from place to place like walking, public transport, etc. We are likely staying near Varanasi station (BSB). Please give your suggestions. All replies are appreciated. 🙏🏻
