Probably a stupid question, I don't know much about this stuff. Is there any reason not to just use a 2.5A even if you're not connecting power-hungry USB devices? If it doesn't cost significantly more and it doesn't hurt to use 2.5 anyway, it's something I'd rather not have to worry about.

Feel free. It'll only draw as much current as it needs. The rating on the power supply is just an upper bound of what it can (theoretically) provide.
