I have 4,300 sf of Chicago brick that needs to be power washed and sealed-sea #green

Which is better--oil based sealers or water based and can I use water based over oil based? I need more information on the care and maintenance of Chicago brick in a climate like Ft. Myers, Florida. The previous owner also used polymeric sand to fill the joints. Is this best or regular sand?
