The array of majors at SUNY-ESF might appeal to you: https://www.esf.edu/admissions/programs.htm
ESF is small (about 1700 undergrads), but it’s immediately adjacent to Syracuse University, with cross-registration and a lot of shared resources, including SU’s abundant disability-related resources including the Disability Cultural Center https://experience.syracuse.edu/dcc and the Center for Disability Resources About CDR - The Center for Disability Resources – Syracuse University as well as the Taishoff Center for Inclusive Higher Learning (a program for students with intellectual and developmental disabilities - not a program that you need, but its presence speaks to the overall commitment to inclusiveness). Applying to SU itself would also be an option; run their Net Price Calculator and see how the aid would look.
RIT is well known as a welcoming destination for students with ASD. (Another aspect of the campus’ inclusiveness is their extensive programming for Deaf students; one of the nation’s two leading Black Deaf scholars teaches there.) Their enviro science program, which has its own 60-acre nature preserve, might appeal to you https://www.rit.edu/study/environmental-science-bs RIT doesn’t guarantee full-need-met aid, but a package that meets need via a combination of need-based aid and merit aid is definitely possible. The downside, here and at many other schools, is that the wraparound support services for ASD come at an extra charge. You may be able to get such programs covered through your local department of voc rehab. Financial Support | Spectrum Support Program | RIT
