Dad has cancer. Best fishing spot for physically disabled/chair accessible

My dad has a very short time to live. He has stage 4 lung cancers that metastasized to his ribs and his brain. He's always wanted to go fishing with me, as have I. We've never gotten this opportunity. I wanted to try to go this Saturday.

Does anybody have any advice in regards to a place that will accommodate his chair? We have a van with a lift for his chair, and he's pretty much bound to the chair so ideally I was trying to find a fishing place where it would be easily accessible for his wheelchair.

My brother is a veteran too, and mentioned cheaper fishing licenses for veterans. Is that true? because my father is a veteran as well and we don't have licenses. Any advice on where to acquire one for cheap?

Also in the market for poles and equipment. Searching OfferUp rn but I genuinely have no idea what I'm looking for. Any pointers would be great. I don't want to purchase bait for bass and then find out there are no bass spots available or it's not their season. Again, I'm totally brand new to this!!
